Bilinear identities on Schur symmetric functions
A series of bilinear identities on the Schur symmetric functions is obtained with the use of Plucker relations.
This paper examines partition as a solution to ethnic civil wars and modifies the ethnic security dilemma, suggesting that strong state institutions are more important than demographically separating ethnic groups to achieve an enduring peace. The paper starts with a puzzle: if ethnic separation is required for peace, how do some partitions that leave minorities behind maintain peace? The paper compares post-partition Georgia–Abkhazia, which experienced violence renewal within five years of the partition, with post-partition Moldova–Transnistria, which maintained peace. Both countries had ‘stay-behind’ ethnic minorities. The paper also disaggregates and compares the territories within post-partition Abkhazia, which contain ethnic Georgians: Lower Gali experienced violence while neighboring Upper Gali did not. The paper argues that state institutions create an incentive for ethnic minorities to collaborate with the state, regardless of minority preferences, and this helps maintain peace. However, preferences become important where institutions are weak and members of the ethnic minority have the opportunity to defect; this increases the likelihood of violence. The results build on the ethnic security dilemma by specifying micro-mechanisms and challenging the theory's reliance on intransigent ethnic identities in explaining the causes of post-partition violence.
We establish a correspondence between Young diagrams and differential operators of infinitely many variables. These operators form a commutative associative algebra isomorphic to the algebra of the conjugated classes of finite permutations of the set of natural numbers. The Schur functions form a complete system of common eigenfunctions of these differential operators, and their eigenvalues are expressed through the characters of symmetric groups. These operators generate differential equations for partition functions of Hurwitz numbers.
The asymptotics of the first rows and columns of random Young diagrams corresponding to extremal characters of the infinite symmetric group is studied. We consider rows and columns with linear growth in $n$, the number of boxes of random diagrams, and prove the central limit theorem for them in the case of distinct Thoma parameters. We also establish a more precise statement relating the growth of rows and columns of Young diagrams to a simple independent random sampling model.
The article considers the Views of L. N. Tolstoy not only as a representative, but also as a accomplisher of the Enlightenment. A comparison of his philosophy with the ideas of Spinoza and Diderot made it possible to clarify some aspects of the transition to the unique Tolstoy’s religious and philosophical doctrine. The comparison of General and specific features of the three philosophers was subjected to a special analysis. Special attention is paid to the way of thinking, the relation to science and the specifics of the worldview by Tolstoy and Diderot. An important aspect is researched the contradiction between the way of thinking and the way of life of the three philosophers.
Tolstoy's transition from rational perception of life to its religious and existential bases is shown. Tolstoy gradually moves away from the idea of a natural man to the idea of a man, who living the commandments of Christ. Starting from the educational worldview, Tolstoy ended by creation of religious and philosophical doctrine, which were relevant for the 20th century.
This important new book offers the first full-length interpretation of the thought of Martin Heidegger with respect to irony. In a radical reading of Heidegger's major works (from Being and Time through the ‘Rector's Address' and the ‘Letter on Humanism' to ‘The Origin of the Work of Art' and the Spiegel interview), Andrew Haas does not claim that Heidegger is simply being ironic. Rather he argues that Heidegger's writings make such an interpretation possible - perhaps even necessary.
Heidegger begins Being and Time with a quote from Plato, a thinker famous for his insistence upon Socratic irony. The Irony of Heidegger takes seriously the apparently curious decision to introduce the threat of irony even as philosophy begins in earnest to raise the question of the meaning of being. Through a detailed and thorough reading of Heidegger's major texts and the fundamental questions they raise, Haas reveals that one of the most important philosophers of the 20th century can be read with as much irony as earnestness. The Irony of Heidegger attempts to show that the essence of this irony lies in uncertainty, and that the entire project of onto-heno-chrono-phenomenology, therefore needs to be called into question.
The article is concerned with the notions of technology in essays of Ernst and Friedrich Georg Jünger. The special problem of the connection between technology and freedom is discussed in the broader context of the criticism of culture and technocracy discussion in the German intellectual history of the first half of the 20th century.
This proceedings publication is a compilation of selected contributions from the “Third International Conference on the Dynamics of Information Systems” which took place at the University of Florida, Gainesville, February 16–18, 2011. The purpose of this conference was to bring together scientists and engineers from industry, government, and academia in order to exchange new discoveries and results in a broad range of topics relevant to the theory and practice of dynamics of information systems. Dynamics of Information Systems: Mathematical Foundation presents state-of-the art research and is intended for graduate students and researchers interested in some of the most recent discoveries in information theory and dynamical systems. Scientists in other disciplines may also benefit from the applications of new developments to their own area of study.
