В статье строится пример диффеоморфизма 33-мерной сферы с положительной топологической энтропией, который имеет одномерное соленоидальное базисное множество с двумерным неустойчивым и одномерным устойчивым инвариантными многообразиями в каждой точке (в частности, базисное множество не является ни аттрактором, ни репеллером). Построенный диффеоморфизм служит основой для конструкции недиссипативного быстрого кинематического динамо с одномерным инвариантным соленоидальным множеством. ...

We consider a class of Smale — Vietoris A-diffeomorphisms that are defined using basic A-endomorphisms of manifolds, the dimension of which is less than the dimension of the supporting manifolds of A-diffeomorphisms. The class of Smale — Vietoris diffeomorphisms contains DE-mappings of Smale. We show that there is a one-to-one correspondence between the basic sets ...

In the paper we construct some example of smooth dieomorphism of closed manifold. This dieomorphism has one-dimensional (in topological sense) basic set with stable invariant manifold of arbitrary nonzero dimension and the unstable invariant manifold of arbitrary dimension not less than two. The basic set has a saddle type, i.e. is neither attractor nor repeller. ...

В статье установлена взаимосвязь между сопряжением диффеоморфизмов Смейла-Виеториса и сопряжением соответствующих неособых эндоморфизмов окружности, а именно, получено необходимое условие сопряженности ограничений диффеоморфизмов Смейла-Виеториса на базовых многообразиях. Показано, что одним из необходимых условий сопряженности рассматриваемого класса диффеоморфизмов является сопряженность соответствующих эндоморфизмов окружности. В работе также доказана техническая теорема, в которой получены некоторые достаточные условия существования гомеоморфизма ...

A meromorphic differential on a Riemann surface is said to be real-normalized if all its periods are real. Real-normalized differentials on Riemann surfaces of given genus with prescribed orders of their poles form real orbifolds whose topology is closely related to that of moduli spaces of Riemann surfaces with marked points. Our goal is to ...

The paper investigates possible ways to take into account risks, caused by uncertain factors, using the problem of optimal deposit diversification as an applied example. It is assumed that the investor (Decision Maker - DM) does not know future exchange rates at the end of the deposit period, and focuses only on some limits of ...

Institutional development tends to converge to several equilibriums differentiating by the level of development. Institutions external to a country, can help this country to find a “right” equilibrium. CEECs countries on average have institutional performance and economic development below the EU15 average. By choosing the Acquis Communautaire as external anchor CEECs may further improve their ...

We study set-valued mappings of bounded variation of one real variable. First we prove the existence of an extension of a metric space valued mapping from a subset of the reals to the whole set of reals with preservation of properties of the initial mapping: total variation, Lipschitz constant or absolute continuity. Then we show ...

In this note, we consider a single machine scheduling problem with generalized total tardiness objective function.
A pseudo-polynomial time solution algorithm is proposed for a special case of this problem. Moreover, we present a new
graphical algorithm for another special case, which corresponds to the classical problem of minimizing the weighted number
of tardy jobs on a single ...

Sequential state discrimination is a strategy for quantum state discrimination of a sender’s quantum
states when N receivers are separately located. In this report, we propose optical designs that can
perform sequential state discrimination of two coherent states. For this purpose, we consider not
only binary phase-shifting-key (BPSK) signals but also general coherent states, with arbitrary prior
probabilities. Since ...

Given an action of an affine algebraic group with only trivial characters on a factorial variety, we ask for categorical quotients. We characterize existence in the category of algebraic varieties. Moreover, allowing constructible sets as quotients, we obtain a more general existence result which, for example, settles the case of a finitely generated algebra of ...

Urban greenery such as trees can effectively reduce air pollution in a natural and eco-friendly way. However, how to spatially locate and arrange greenery in an optimal way remains as a challenging task. We developed an agent-based model of air pollution dynamics to support the optimal allocation and configuration of tree clusters in a city. The Pareto ...

We associate an explicit equivalent descendent insertion to any relative insertion in quantum K-theory of Nakajima varieties.
This also serves as an explicit formula for off-shell Bethe eigenfunctions for general quantum loop algebras associated to quivers and gives the general integral solution to the corresponding quantum Knizhnik Zamolodchikov and dynamical q-difference equations. ...

В предлагаемом пособии содержатся задачи различного уровня сложности. Однако основной акцент сделан на задачах средней сложности. Это сделано намеренно с тем, чтобы побудить студентов к самостоятельному решению задач: слишком простые задачи решать скучно; слишком сложные демотивируют средних и слабых студентов, а у сильных студентов зачастую отнимают неоправданно большое количество времени, которым в реальном учебном процессе они не обладают.
