In this ambitious two-volume open access collection of essays, a diverse group of scholars worldwide reflects on the past, present and future of the (comparative) regionalism research program. Volume I provides building blocks for regionalism studies in the coming years by indicating what a pluralistic theoretical and methodological toolbox to study regions could look like, ...

We consider solutions of the matrix Kadomtsev-Petviashvili (KP) hierarchy that are trigonometric functions of the first hierarchical time t1 = x and establish the correspondence with the spin generalization of the trigonometric Calogero-Moser system at the level of hierarchies. Namely, the evolution of poles xi and matrix residues at the poles aαibβi of the solutions with respect to the kth hierarchical time of the ...

We consider solutions of the Kadomtsev–Petviashvili hierarchy which are elliptic functions of x = t1. It is known that their poles as functions of t2 move as particles of the elliptic Calogero–Moser model. We extend this correspondence to the level of hierarchies and find the Hamiltonian Hk of the elliptic Calogero–Moser model which governs the dynamics of poles with respect to the kth ...

We consider solutions of the 2D Toda lattice hierarchy which are elliptic functions of the zeroth time t_0=x. It is known that their poles as functions of t_1 move as particles of the elliptic Ruijsenaars-Schneider model. The goal of this paper is to extend this correspondence to the level of hierarchies. We show that the ...

We continue the study of the B-Toda hierarchy (the Toda lattice with the constraint of type B), which can be regarded as a discretization of the BKP hierarchy. We introduce the tau function of the B-Toda hierarchy and obtain bilinear equations for it. Examples of soliton tau functions are presented in explicit form. ...

The increasingly rapid process of de-dollarization in the context of growing geopolitical fragmentation has significantly altered the monetary dynamics of the global economy, thereby posing important questions about economic resilience and sustainable development in the emerging world. This research investigates de-dollarization-related macro-financial conditions and their association with economic resilience in the BRICS+ countries during the ...

Данная монография посвящена анализу концепции суверенитета африканских государств как в теоретическом, так и практическом ключе. Рассматриваются экономический, ментальный, языковой и культурный, информационный и образовательный аспекты африканского суверенитета. Исследуется роль региональных интеграционных группировок, а также внешних акторов в контексте суверенизации Африки. Особое внимание уделяется роли РФ в укре- плении суверенитета стран континента.
Монография формирует целостное представление по ...

A well-studied class of algorithmic problems is that of regular realizability: checking the non-emptiness of the intersection of a regular language with a given language. This problem has a natural algebraic interpretation: verifying whether an element of a Boolean algebra belongs to the kernel of a certain homomorphism. This motivates the consideration of an analogous ...

The paper presents a solution to the question about the decidability of the two-variable fragment of the superintuitionistic predicate logic QLC defined by the class of linear Kripke frames, which is also the ‘superintuitionistic’ fragment of the modal predicate logic QS4.3, under the Gödel translation. We prove that the fragment is undecidable. The result remains true for the ...

In the coming millennium, the transformation of our world has become a matter
of global concern. The first attempts to move in this direction were unsuccessful.
The globalization of economic activity is being replaced by the formation of relatively
autonomous macroregions. But it would be a mistake to assume on this
basis that joint dominion over the entire planet ...

This paper analyzes discrepancies between direct and mirror data in Russia's foreign trade statistics over the period of 2003-2024. Special attention is given to assessing the impact of sanction policies on the level of statistical discrepancies, which reflect trade costs, manipulations in customs and tax reporting, as well as structural changes in logistics and the ...

This paper investigates the problem of statistical inference for a mixture distribution consisting of a discrete and a continuous component, with a particular focus on the class of rational-infinitely divisible distributions. We consider non-parametric estimation of both components of the mixture as well as the quasi-L{é}vy measure, assuming that the mixture belongs to the class ...

This paper studies the technical efficiency of Russian retail companies in 2019 to 2023 using stochastic frontier analysis (SFA) with the Battese and Coelli (1995) model. A translogarithmic production function is employed for estimations. The dependent variable is company revenue, and the production factors are the average number of employees, fixed assets, and assets less ...

Within narrowly defined industries, the most productive firms produce far more than the least productive from the same inputs, and this dispersion widens in downturns. We build a tractable representative-agent model in which financial frictions—adverse selection and moral hazard—make firms sort endogenously into lenders, strategic defaulters, and producers. As credit conditions vary, the resulting misallocation ...

В аналитической записке обсуждается долгосрочно устойчивый уровень цены на российскую нефть. Это тот уровень, к которому цена нефти, вероятнее всего, будет тяготеть в долгосрочной перспективе. Потребность в его определении возникает по нескольким причинам. Во-первых, цена на нефть остается одним из ключевых экономических показателей российской экономики, определяющих экспорт, обменный курс рубля, прибыль, доходы и расходы бюджета, ...

The paper proposes a graphical model of a small open economy. The dynamics of the graphical model is then illustrated using impulse responses from the corresponding formal semi-structural model (QPM model). The authors have several goals in preparing this description of the graphical macroeconomic model. The first goal of the paper is to present an adapted ...

In this paper, we construct strong approximations for discrete-time Markov chains weakly converging to continuous diffusion processes, as well as for their perturbed counterparts. Under the assumption of bounded coefficients, we construct closely coupled versions of these processes on a shared probability space. In particular, for both non-degenerate and degenerate cases, we maximize the probability ...
