Non-axiomatizability of modal predicate logics of Dedekind-complete linear orders with constant domains

Rybakov M., Shkatov D., Journal of Logic and Computation 2026 Vol. 36 No. 6 Article exag026

We prove Pi-1-1-hardness, and thus lack of recursive axiomatizability, of constant-domain modal predicate logics defined by a class of Dedekind complete linear Kripke frames containing a frame with an infinitely increasing chain of worlds. The result holds even for the language with one unary predicate letter, one propositional letter, and two individual variables. ...

Semi-Interlaced Polytopes

Селянин Ф. И., Moscow Mathematical Journal 2026 Vol. 26 No. 2 P. 167–187

Minkowski mixed volume of n subpolytopes D1,…,Dn of a polytope P⊂Rn clearly does not exceed the normalized volume n!Vol(P). Equality holds if and only if the subpolytopes are interlaced, i.e., each proper face F⊊P intersects at least dim(F)+1 of the polytopes Di. Efficiently computing mixed volumes for more general collections of subpolytopes is crucial for estimating the complexity of numerically solving polynomial systems. Motivated by relaxing the bound dim(F)+1 to dim(F), we ...

Мотивы распределения суверенного финансирования в Евразийском регионе: пример USAID и АБР

Morozkina A., Есаян М. А., Контуры глобальных трансформаций: политика, экономика, право 2025 Т. 18 № 4 С. 169–190

In the context of budget constraints, the allocation of development finance is one of the important research questions. This article proposes a study of the allocation of sovereign financing in the Eurasian region in 2008-2022 using new data (the Eurasian Fund for Stabilization and Development (EFSD) sovereign financing database). The analysis shows that the most ...

Beyond the Binary: A Theoretical Exploration of Gendered Experiences for Women in Nigerian STEM Education

Asia and Africa today 2026 Vol. 6 P. 80–86

This theoretical article examines the persistent problem of the “leaky pipeline” for women in Nigerian higher education, where increased representation in male-dominated STEM fields is undermined by enduring stereotypes and socio-cultural barriers. By employing a critical theoretical analysis and interpretive synthesis, it aims to demonstrate how the concept of reflexive modernization explains why stereotype threats ...

A new spin on polynomial relations among kappa classes

Kazaryan M., Dunin-Barkowski P., Bychkov B. et al., International Mathematics Research Notices 2026 Vol. 14 Article rnag146

We prove a recent conjecture of the fourth named author with P. Norbury that states a system of universal polynomial relations among the kappa classes on the moduli spaces of algebraic curves. The proof involves localization and materialization analysis of the spin Gromov–Witten theory of the projective line and is dictated by Z 2 -equivariant ...

Any Topological Recursion on a Rational Spectral Curveis KP Integrable

Kazaryan M., Dunin-Barkowski P., Bychkov B. et al., Communications in Mathematical Physics 2026 Vol. 407 No. 69

We prove that for any initial data on a genus zero spectral curve the cor responding correlation differentials of topological recursion are KP integrable. As an application we prove KP integrability of partition functions associated via ELSV-type formulas to the r-th roots of the twisted powers of the log canonical bundles ...

Artificial intelligence and the reconfiguration of competency management systems in organizations

Asemota M. O., DISCOVER ARTIFICIAL INTELLIGENCE 2026 Vol. 6 Article 892

Artificial intelligence (AI) is reshaping work and human resource management, yet existing reviews largely treat competencies as secondary outcomes of AI adoption and offer limited theory-driven integration of how competency management itself is transforming. This study addresses that gap by systematically examining how competency management has evolved in AI-enabled contexts, how dominant theories explain AI-driven ...

Socio‑humanitarian knowledge helps to master the social norms and values of Russian civilization. Each module of social studies is linked to a specific sphere of human social life, to activities aimed at fulfilling a person’s spiritual needs and social interests. Recognizing the social nature of one’s own needs is an important step towards understanding oneself, ...

Gromov V., Переслегин С. Б., Переслегина Е. Б. et al., СПб.: Полакс, 2026.

Механизм происходящих в мире изменений носит эволюционный, а не экологический характер. Иначе говоря, Человечество столкнулось с кризисом развития, который имеет три независимые составляющие: кризис индустриального общества (фазовый кризис), кризис научного мышления (эпистемный кризис) и кризис формата существования разума (социосистемный кризис). Доклад посвящён аспектам этого триединого кризиса и возможным путям его преодоления, не сводящимся к первичному ...

We give a proof of Mukai’s theorem on the existence of certain exceptional vector bundles on prime Fano threefolds. To our knowledge this is the first complete proof in the literature. The result is essential for Mukai’s biregular classification of prime Fano threefolds, and for the existence of semiorthogonal decompositions in their derived categories. Our ...

Full exceptional collections on the symplectic isotropic Grassmannians

Guseva L., Novikov A., Advances in Mathematics 2026 Vol. 503 Article 111211

We prove that the Kuznetsov–Polishchuk exceptional collections on rational homogeneous spaces of the symplectic groups Sp(2n,C) are full and consist of vector bundles. To achieve this, we construct several classes of complexes, which we call generalized staircase complexes, symplectic staircase complexes and secondary staircase complexes — each of which may be of independent interest. ...

We prove that for every relatively prime pair of integers (d,r) with r>0, there exists an exceptional pair (O,V) on any del Pezzo surface of degree 4, such that V is a bundle of rank r and degree d. As an application, we prove that every Feigin-Odesskii Poisson bracket on a projective space can be ...

Vanishing Vanguard: Decline of Leadership in Revolutionary Mass Mobilization since the 19th Century

Ustyuzhanin V., Zinkina J. V., Korotayev A., / Series "SocArXiv". 2026.

“Leaderlessness” is widely held to be a defining feature of contemporary mass mobilization, yet the claim rests on a handful of recent cases. We offer the first systematic cross-national analysis of this phenomenon from 1791 to 2019. We show that the absence of leadership is real but older and more modest than claimed: the share ...

Стремительное развитие генеративного искусственного интеллекта (генИИ) усилило дискуссии о том, как новые технологии трансформируют рынок труда, особенно позиции и задачи, которые еще недавно мог выполнять только человек. Эксперименты показывают, что генеративный ИИ может обеспечить значительный прирост производительности, особенно менее квалифицированных сотрудников, что может приводить к возникновению индивидуальной зарплатной отдачи на рынке труда. Впервые для России ...
