This article is dedicated to the study of time category in the English folktale „The Seal-Catcher”. Folktale has always been considered as the unique component of folklore. All peoples of the world have been describing the ...

We prove that the semigroup of matrix units is stable. Compact, countably compact and pseudocompact topologies on the infinite semigroup of matrix units B such that (B , ) is a semitopological (inverse) semigroup are ...

A subset D of the vertex set of a connected graph G is called a total global neighbourhood dominating set(tgnd-set) of G if and only if D is a total dominating set of G as well as GN , where GN is the neighbourhood graph ...

The article is devoted to defining the transformational processes of logistics activities of corporate enterprises. The financial and economic factors of increasing the investment attractiveness of transport and logistics ...

Let D = (V, A) be a finite simple directed graph (shortly digraph). A function f : V −→ {−1, 1} is called a twin signed dominating function (TSDF) if f(N −[v]) > 1 and f(N +[v]) > 1 for each vertex v ∈ V . The twin signed ...

We study the class of standardly stratified alge- bras introduced by Cline, Parshall and Scott, and its subclass of the so-called weakly properly stratified algebras, which generalizes the class of properly stratified ...

The article reveals the meaning of the concept of organizational structure; approaches to the formation of the management structure were studied, a typology of organizational structures was formed, their advantages and ...

In this paper, we show that if P(x) = Pm k=0 akx k is a polynomial with nondecreasing, nonnegative coefficients, then the coefficients sequence of P(x s + · · · + x + 1) is unimodal for each integer s > 1. This ...

The article discusses the scientific experience of using the „alternative history” method in the study of the history of the Second World War. The authors revealed the peculiarities of the methodology for applying ...

On the basis of various computer models (classical one-dimensional and author's multidimensional – systems of equations) of nonlinear economic dynamics, the demographic impact on economic growth scenarios is studied, but ...
