Стабилизация линейных стохастических систем с дисконтированием: моделирование долгосрочных эффектов применения оптимальных стратегий управления
Математическое моделирование. 2015. Т. 27. № 1. С. 3–15.
We consider a problem of stabilization of linear stochastic control systems. The quadratic cost functional measures the total loss resulting from deviation of the process and control from their target levels. It includes the decision maker’s time preference expressed by means of discount function. We study the long-run impacts of average optimal policies in terms of mean-square deviation of optimal trajectory from its target and also in an almost-sure sense.

We consider 3-diffeomorphisms with source–sink dynamics where Smale solenoids play the role of the source and the sink (NSSS-diffeomorphisms). It is known that such diffeomorphisms exist only on lens spaces. On the 3-sphere, every NSSS-diffeomorphism is associated with an exchangeable braid. An exchangeable braid with the strand number n was constructed for each n 3 in such a way ...

Гомеоморфизмы топологических пространств называются эквивалентными по надстройке, если надстройки над ними топологически эквивалентны. В частности, топологически сопряженные гомеоморфизмы эквивалентны по надстройке. Известно, что для гомологически неприводимых гомеоморфизмов их топологическая сопряженность является необходимым и достаточным условием их эквивалентности по надстройке. Тогда как инварианты топологической сопряженности гомологически приводимых гомеоморфизмов во многих случаях являются избыточными для эквивалентности по ...

Elaborating on Welzel et al.'s "Cool Water Theory," our study zooms into the more limited (albeit still varied) framework conditions of Russia's huge territory. Within Russia's confines, we examine how the combination of moderately cool seasons with steady rain (i.e., Cool Water) affects sub-national areas' contemporary societal progress in two modernization indicators: material prosperity in ...

Digital public procurement is increasingly implemented through e-procurement platforms, yet evidence on the governance capabilities needed to deliver transparency, coordination and organisational learning remains limited outside high-capacity contexts. This article reframes public procurement as a socio-technical platform ecosystem and develops an ecosystem capability framework that links three tiers (government, platform operators and users) to three ...

Small and medium-sized enterprises (SMEs) operate under conditions of chronic resource constraints, which makes it important to study strategies capable of transforming available resources into sustainable financial outcomes. One such strategy is entrepreneurial bricolage - the unconventional recombination of existing resources to address organizational challenges. This article examines the impact of bricolage on SME performance, ...

Пусть M обозначает симметрическое пространство некомпактного типа ранга 1. Опираясь на фундаментальную работу [1], в [2] было показано, что плотность соответствующим образом нормированной суммы независимых Hn-значных случайных величин, определенная через сложение Мёбиуса в модели шара Пуанкаре, сходится к фундаментальному решению соответствующего уравнения теплопроводности. Пределом являлся нормальный закон на Hn, соответствующий ядру теплопроводности, определяемому оператором Лапласа–Бельтрами. ...

Purpose
This study assesses the impact of the European Central Bank's (ECB) Unconventional Monetary Policy (UMP) on economic growth via its effects on sovereign bond yields in the Eurozone. Unlike previous studies that focus on high-frequency data and short-term effects, this study provides evidence on the long-term effects of the ECB's asset purchases on key macroeconomic ...

The paper examines changes in the economic affordability of cigarettes in Russian regions in 2011–2023. Using fixed-effects models, it estimates the impact of prices, incomes, and tobacco affordability (the ratio of per capita income to cigarette price), on three indicators: retail sales of cigarettes per capita, adult population spending on tobacco products, and the share of these ...

At the end of 2023, Russia updated its Strategy for Improving Financial Literacy and Developing Financial Culture Until 2030. Unlike the previous strategy, the current strategic goals include not only financial literacy but also financial culture. ‘Culture’ is normative and socially preferred behaviour. The updated strategy brings into focus the relationship between financial literacy and responsible financial behaviour. To explore this relationship, the authors rely on data from the All-Russian Survey of Consumer Finance (2020 and 2022). Socially ...

A vertex subset of a graph is called a \textit{distance-$k$ independent set} if the distance between any two of its distinct vertices is at least $k + 1$. For all $n,k \geq 1$, we determine the minimum possible number of inclusion-wise maximal distance-$k$ independent sets among all $n$-vertex trees. It equals~$n$ if $n \leq k ...

We deal with the global in time weak solutions to the 1D compressible Navier-Stokes system of equations for large discontinuous initial data and nonhomogeneous boundary conditions of three standard types. We prove the Lipschitz-type continuous dependence of the solution $(\eta,u,\theta)$, in a norm slightly stronger than $L^{2,\infty}(Q)\times L^2(Q)\times L^2(Q)$, on the initial data $(\eta^0,u^0,e^0)$ in a ...

This paper proposes Covariate-Balanced Weighted Stacked Difference-in-Differences (CBWSDID), a design-based extension of weighted stacked DID for settings in which untreated trends may be conditionally rather than unconditionally parallel. The estimator separates within-subexperiment design adjustment from across-subexperiment aggregation: matching or weighting improves treated-control comparability within each stacked subexperiment, while the corrective stacked weights of Wing et ...
