The present study generalizes the results of scientific research in the field of economic and mathematic simulation using elements of the theory of functions of complex variables (TFCV), which was conducted since 2004 under the author’s scientific supervision. Since the new results significantly extend the instrumental basis of scientific research in economics and possess their own theoretical base and logic, this section of economic and mathematic simulation was called “complex economics”. The study provides the fundamentals of this new scientific direction in economics and demonstrates how to use this theoretical base to build new economic and mathematic models that appear to be more adequate than models of real variables.
Most economists are absolutely unfamiliar or slightly familiar with the theory of functions complex variables. This is why, in this study, we would state briefly some provisions of this theory to get the reader acquainted with TFCV, and then formulate sequentially the principles of the theory of complex economy, its axiomatic core, basic conceptual positions of the theory, methods and models of the complex economics. Where necessary, theoretical provisions are verified by examples from the real economic practice.
The study is targeted at scientific workers, post-graduate students and doctors using economic and mathematic simulations in their activity.

It is more than 10 years ago that the first edition of this book has appeared. Since then, the field of computational invariant theory has been enjoying a lot of attention and activity, resulting in some important and, to us, exciting developments. This is why we think that it is time for a second enlarged and revised edition. Apart from correcting some mistakes and reorganizing the presentation here and there, we have added the following material: further results about separating invariants and their computation (Sects. 2.4 and 4.9.1), Symonds’ degree bound (Sect. 3.3.2), Hughes’ and Kemper’s extension of Molien’s formula (Sect. 3.4.2), King’s algorithm for computing fundamental invariants (Sect. 3.8.2), Broer’s criterion for the quasi- Gorenstein property (Sect. 3.9.11), Dufresne’s generalization of Serre’s result on polynomial invariant rings and her result with Jeffries (Sect. 3.12.2), Kamke’s algorithm for computing invariants of finite groups acting on algebras (Sect. 3.13), Kemper’s and Derksen’s algorithm for computing invariants of reductive groups in positive characteristic (Sect. 3.13), algorithms by Müller-Quade and Beth, Hubert and Kogan, and Kamke and Kemper for computing invariant fields and localizations of invariant rings (Sect. 4.10.1), and work by van den Essen, Freudenburg, Greuel and Pfister, Kemper, Sancho de Salas, and Tanimoto on invariants of the additive group and of connected solvable groups (Sect. 4.10.5).
Last but not least, this edition contains two new appendices, written by Vladimir Popov, on algorithms for deciding the containment of orbit closures and on a stratification of Hilbert’s nullcone. The second appendix has an addendum, authored by Norbert A’Campo and Vladimir Popov, containing the source code of a program for computing this stratification. We would like to thank Bram Broer, Emilie Dufresne, Vladimir Popov, Jim Shank, and Peter Symonds for valuable comments on a pre-circulated version of this edition, Vladimir Popov and Norbert A’Campo for their contributions to the book, and Ruth Allewelt at Springer-Verlag for managing the production process and for gently pushing us to finally finish our work and hand over the files.

Computer simulations are nowadays a rmly established third pillar of modern natural sciences, complementing experimentation and paper-and-pencil theoret- ical studies. Simulations, experiments in silico, prove indispensable in diverse areas of research in physics and other natural sciences. This volume collects papers based on presentations delivered at the Sec- ond International Conference on Computer Simulations in Physics and beyond (CSP2017), which took place October 9-12, 2017 in Moscow. The Conference, which continues a biannual tradition started by an innaugural conference in 2015, took place on campus of A.N. Tikhonov Moscow Institute of Electronics and Mathematics, was jointly organized by the National Research University Higher School of Economics, the Landau Insitute for Theoretical Physics and Science Center in Chernogolovka. As the name implies, the Conference is a multidisciplinary meeting, with a focus on computational physics and related subjects. Indeed, methods of computational physics prove useful in a broad spectrum of research in multiple branches of natural sciences, and this volume provides a sample. We hope that this volume will interest a wide range of readers, and we are already looking forward for the next conference in this biannual series.
In this paper, we study the Maximum Happy Vertices and the Maximum Happy Edges problems (MHV and MHE for short). Very recently, the problems attracted a lot of attention and were studied in Agrawal ’17, Aravind et al. ’16, Choudhari and Reddy ’18, Misra and Reddy ’17. Main focus of our work is lower bounds on the computational complexity of these problems. Established lower bounds can be divided into the following groups: NP-hardness of the above guarantee parameterization, kernelization lower bounds (answering questions of Misra and Reddy ’17), exponential lower bounds under the Set Cover Conjecture and the Exponential Time Hypothesis, and inapproximability results. Moreover, we present an O∗(ℓk)O∗(ℓk) randomized algorithm for MHV and an O∗(2k)O∗(2k) algorithm for MHE, where ℓℓ is the number of colors used and k is the number of required happy vertices or edges. These algorithms cannot be improved to subexponential taking proved lower bounds into account.
dance4life is a globally active organization within the fields of HIV, sexual and reproductive health and rights (SRHR) and the Millennium Development Goals, specifically aiming to establish a social youth movement consisting of 1 million agents4change by 2014. The central mission of dance4life is to power a movement that creates change at global and community level by taking action to improve young people’s SRHR, and in particular, improving access to sexuality education and youth-friendly services, and to challenge stigma and discrimination and break down taboos that surround sexuality, especially focusing on HIV and AIDS. KIT was invited to partner with dance4life on an impact assessment of dance4life’s work, with a focus on mixed methods and the involvement of the young people themselves. The assessment took place in two countries: Uganda and Russia. A pilot study was undertaken in the Netherlands to test the qualitative research instruments.
This is the first textbook on attribute exploration, its theory, its algorithms for applications, and some of its many possible generalizations. Attribute exploration is useful for acquiring structured knowledge through an interactive process, by asking queries to an expert. Generalizations that handle incomplete, faulty, or imprecise data are discussed, but the focus lies on knowledge extraction from a reliable information source.
The method is based on Formal Concept Analysis, a mathematical theory of concepts and concept hierarchies, and uses its expressive diagrams. The presentation is self-contained. It provides an introduction to Formal Concept Analysis with emphasis on its ability to derive algebraic structures from qualitative data, which can be represented in meaningful and precise graphics.
This book constitutes the proceedings of the 20th International Conference on Conceptual Structures, ICCS 2013, held in Mumbai, India, in January 2013. The 22 full papers presented were carefully reviewed and selected from 43 submissions for inclusion in the book. The volume also contains 3 invited talks. ICCS focuses on the useful representation and analysis of conceptual knowledge with research and business applications. It advances the theory and practice in connecting the user's conceptual approach to problem solving with the formal structures that computer applications need to bring their productivity to bear. Conceptual structures (CS) represent a family of approaches that builds on the successes of artificial intelligence, business intelligence, computational linguistics, conceptual modeling, information and Web technologies, user modeling, and knowledge management.
This book constitutes the refereed proceedings of the 17th International Conference on Conceptual Structures, ICCS 2009, which took place in Moscow, Russia, on July 26-31, 2009.
The 18 papers presented together with 5 invited contributions were carefully reviewed and selected from approximately 50 submissions. Originally centered around research on knowledge representation and reasoning with conceptual graphs, over the years ICCS has broadened its scope to include innovations from a wider range of theories and related practices, among them other forms of graph-based formalisms like RDF or existential graphs, formal concept analysis, semantic Web technologies, ontologies, concept mapping and more.
L’ouvrage est le fruit de deux programmes internationaux de recherche :«Confessiones et nationes. Traditions confessionnelles dans la formation des discours proto-nationaux et nationaux en Europe : fondements médiévaux, évolutions modernes et effets contemporains» , organisé par le Centre d’études ukrainiennes et biélorusses de l’Université Lomonossov de Moscou, aussi que de la journée d’étude « Nations et religions », organisée par l’Université Paris IV Sorbonne en 2009. Le projet global ambitionnait de trouver des éléments de réponse à trois grandes questions : Primo : comment les spécificités confessionnelles des christianismes « latin » et « grec » ont influées sur la construction des discours proto-nationaux, aux époques médiévale et moderne, dans les milieux orthodoxes, catholiques et protestants, en Europe ? Secundo : quelle fut, dans la perspective comparative de la longue durée, l’influence des discours identitaires médiévaux sur les représentations et les pratiques des discours nationaux et nationalistes des XIXe et XXe siècles ? Tertio : comment les spécificités confessionnelles des christianismes « latin » et « grec » ont-elles pesées sur la construction des discours supranationaux et a-nationaux, aux époques médiévale et moderne, et, éventuellement aux XIXe et XXe siècles ? Les études proposées dans ce volume apportent des éléments de reponse à ces grandes questions.
On 15 March 2019, the first “Connecting Eurasia Dialogue: From the Atlantic to the Pacific” was held in Brussels, at Europe’s political heart. The event was organized by the Roscongress Foundation and the Conoscere Eurasia Association with the support of the Association of European Businesses and the Belgian-Luxembourg Chamber of Commerce. Amid the current political cooldown, this was a unique gathering, enabling a high-level dialogue on trade, economic, and integration issues among stakeholders from the wider Eurasian space, including the European Union (EU), the Eurasian Economic Union (EAEU), and China. The focus of high-level policy makers and top business executives attended the Dialogue was on challenges and opportunities of the EU’s engagement with the EAEU, harmonization of soft infrastructure to enhance trans-Eurasian connectivity, and the EAEU’s single pharmaceutical market. This IIASA discussion paper provides a summary of the deliberations, supported by research from inside and outside the Institute.
Derived from the renowned multi-volume International Encyclopaedia of Laws, this very useful analysis of constitutional law in Russia provides essential information on the country's sources of constitutional law, its form of government, and its administrative structure. Lawyers who handle transnational matters will appreciate the clarifications of particular terminology and its application. Throughout the book, the treatment emphasizes the specific points at which constitutional law affects the interpretation of legal rules and procedure.
Thorough coverage by a local expert fully describes the political system, the historical background, the role of treaties, legislation, jurisprudence, and administrative regulations. The discussion of the form and structure of government outlines its legal status, the jurisdiction and workings of the central state organs, the subdivisions of the state, its decentralized authorities, and concepts of citizenship. Special issues include the legal position of aliens, foreign relations, taxing and spending powers, emergency laws, the power of the military, and the constitutional relationship between church and state. Details are presented in such a way that readers who are unfamiliar with specific terms and concepts in varying contexts will fully grasp their meaning and significance.
Its succinct yet scholarly nature, as well as the practical quality of the information it provides, make this book a valuable time-saving tool for both practising and academic jurists. Lawyers representing parties with interests in Russia will welcome this guide, and academics and researchers will appreciate its value in the study of comparative constitutional law.
quarter of a century has passed since the Constitution of the Russian Federation was adopted in 1993, yet the issue of the results and the prospects for constitutional transformation has not disappeared from the political agenda. For some, the Constitution signifies an ultimate break up with the communist past and a legal foundation for the advancement of the Russian society toward democracy and the rule of law; for the others, it is exactly the Constitution that is the culprit for the authoritarian trend that has prevailed, and for the sustained stagnation in Russia’s economic, social and political development. The author of this chapter is in the middle of these extreme viewpoints. He believes that the Constitution has truly played a pivotal role in Russia’s move toward democracy by establishing the basic principles of civil society and the rule of law, and in this respect, it remains of everlasting and paramount importance. Nevertheless, that does not mean that it should be utterly inaccessible for changes, especially given the elapsed time and the negative experience of the authoritarian transformation of the political regime, the amendments that were introduced between2008 and 2014, and the current objectives of the democratic movement. The rationale for changes is to return to the constitutional principles, reaffirm their initial democratic meaning by rejecting the excessive concentration of the Presidential power, the results of counter-reforms and the adulteration through legislative and regulatory compliance practices. Some of the proposed remedies aim to establish a new form of government (Presidential - Parliamentary), which would necessitate Constitutional amendments — adjustments that would regulate the separation of powers and redistribution of authority. Others seek to transform the system without changing the text of the Constitution through legislative reforms, judicial interpretation and the policy of law. Yet, the third approach prioritizes institutional reforms. Not everything in social development depends on the provisions of the law, political improvisation and practice can prove just as critical. In their cumulative entirety such initiatives can help avoid the two extremes: that of constitutional stagnation gravitating toward the bureaucratic asphyxiation, and that of constitutional populism which has a tendency to destabilize the political system. In its practical activities to transform the political regime, the opposition ought to remember the maximum repeatedly confirmed by experience, — the further a party is from power, the more radical tend to be its constitutional proposals. Conversely, empowered groups tend to be more moderate in their initiatives.
