Complexity Studies: Interdisciplinarity in Action
Ch. 18. P. 379–402.
Modern complexity studies and their interdisciplinary character are under consideration in this article. The conceptual framework of complexity studies includes such methodologically significant notions as nonlinearity, self-organization, creative chaos, co-evolution and blow-up regimes. It is argued that interdisciplinarity corresponding to a holistic worldview becomes a powerful trend in modern science. At the same time, evolutionary holism constitutes a philosophical basis for complexity studies. The possible future developments of complexity studies as a fundamental interdisciplinary paradigm are discussed as well. It is shown that interdisciplinary research will define the character of science in the medium-term future.

Вдохновляясь некоторыми идеями из логического программирования, Мелвин Фиттинг в [Fitting 1997] предложил свою собственную модификацию теории истины по Крипке. Пусть T обозначает соответствующий монотонный оператор. Мы показываем, что: 1) замыкающий ординал для T равен $\omega_1^{СК}$, т.е. наименьшему неконструктивному ординалу; 2) совокупность всех предложений, истинных согласно T_⋆ является $\Pi^1_1$-полной. ...

Studies of more-than-human sociality in general, and multispecies ethnography in particular, are becoming an increasingly popular trend in global (social, human, and transdisciplinary) scholarship. In the current forum, researchers from various disciplines discuss the advantages, limitations, and challenges of this trend. They also share their thoughts on why multispecies research has (or has not) an ...

Tis paper presents a novel approach to analyzing and grouping natural languages based on the degree of their chaoticity. It clusters 52 languages from 18 language families, according to the value of the entropy–complexity pair, to reveal the chaotic properties of semantic trajectories. Te obtained clusters appear to be closely correlated with the family of ...

В настоящей статье изучаются вычислительные аспекты формального требования максимальной специфичности, накладываемого на правила в языке пропозициональной классической логики, когда над этим языком задана вычислимая рационально-значная вероятностная мера. Доказана неразрешимость ряда общих проблем по обнаружению максимально специфичных правил и вероятностных мер, для которых совокупность всех специфичных правил вычислима; установлена разрешимость множества максимально специфичных правил при неких ...

In the present article, the quantifiers over propositions are first introduced into the language for reasoning about probability, then the complexity issues for validity problems dealing with the corresponding hierarchy of probabilistic sentences are investigated. We prove, among other things, the $\Pi^1_1$-completeness for the general validity and also indicate the least level in the hierarchy ...

The paper contains a survey on the complexity of various truth hierarchies arising in Kripke’s theory. I present some new arguments, and use them to obtain a number of interesting generalisations of known results. These arguments are both relatively simple, involving only the basic machinery of constructive ordinals, and very general. ...

We introduce infinitary action logic with exponentiation — that is, the multiplicative-additive Lambek calculus extended with Kleene star and with a family of subexponential modalities, which allow some of the structural rules (contraction, weakening, permutation). The logic is presented in the form of an infinitary sequent calculus. We prove cut elimination and, in the case ...

Пусть $\mathsf{QPL}$ – предложенный в [Speranski 2017] двусортный вероятностный язык, который расширяет хорошо известный «полиномиальный» язык, описанный в [Fagin et al. 1990, раздел 6], посредством добавления кванторов по событиям. Мы показываем, что все безатомные пространства имеют одну и ту же $\mathsf{QPL}$-теорию и эта теория разрешима. Также мы вводим понятие элементарного инварианта для QPL и используем его для ...

Infinitary action logic can be naturally expanded by adding exponential and subexponential modalities from linear logic. In this article we shall develop infinitary action logic with a subexponential that allows multiplexing (instead of contraction). Both non-commutative and commutative versions of this logic will be considered, presented as infinitary sequent calculi. We shall prove cut admissibility ...

This paper is concerned with a two-sorted probabilistic language, denoted by QPL, which contains quantifiers over events and over reals, and can be viewed as an elementary language for reasoning about probability spaces. The fragment of QPL containing only quantifiers over reals is a variant of the well-known ‘polynomial’ language from [Fagin et al. 1990, Section 6]. ...

We shall be concerned with two natural expansions of the quantifier-free ‘polynomial’ probability logic of [Fagin et al. 1990]. One of these, denoted by QPL-e, is obtained by adding quantifiers over arbitrary events, and the other, denoted by p-QPL-e, uses quantifiers over propositional formulas — or equivalently, over events expressible by such formulas. The earlier proofs ...

В данной статье рассматривается развитие и текущее состояние благотворительности и самоорганизации в Канаде. Анализ литературы и государственных статистических баз данных показал, что основное финансирование деятельности благотворительных организаций в Канаде осуществляет государство, в особенности бюджеты провинций. Вместе с тем канадскому некоммерческому сектору присущи широкое вовлечение волонтеров, сложившаяся практика добровольных индивидуальных пожертвований и система налоговых вычетов на ...

The article examines the current state of the methodological framework of cultural sciences. In the context of modern social changes, an interdisciplinary approach combining anthropology, sociology, cultural studies and media studies is proving ineffective. «Strong» theoretical concepts such as «globalization», «glocalization», «digitalization», «postcolonialism», the concept of the Global South, as well as other «meta-ideas» often ...

Building on foundational work in systems theory, thermodynamics, and evolutionary theory, this paper argues that complexity can serve as a conceptual bridge across disciplines. It explores the role of complexity dynamics in Big History through an integrative theoretical framework that spans physical, chemical, geological, biological, social, cognitive, and civilizational domains. By examining how complexity emerges, ...
