This article outlines the most important barriers for Bulgarian and Polish students that abandon or significantly reduce the execution of their entrepreneurial intentions and the start of new businesses. There are significant ...
• (Луганский национальный университет им. Т. Шевченко, 2004)
A concept of basic matrix semigroups over fields (with some variations) is introduced and throughly investigated. Sections 1 and 2 contain main definitions, Section 3 treats some properties of basic semigroups, Section 4 ...

The processes of globalization, modern educational trends, changing values, rapid development of science, increasing business and personal contacts with speakers of other cultures necessitate the education of bilingual ...

We describe the C -algebra generated by four orthogonal projections p1, p2, p3, p4, satisfying the linear relation p1 + p2 + p3 + p4 = 2I. The simplest realization by 2 × 2-matrixfunctions over the sphere S2 is given.

We completely determine all commutative semigroup varieties that are cancellable elements of the lattice SEM of all semigroup varieties. In particular, we verify that a commutative semigroup variety is a cancellable element ...

A major part of Iyama’s characterization of Auslander-Reiten quivers of representation-finite orders consists of an induction via rejective subcategories of ¤-lattices, which amounts to a resolution of ¤ as an isolated ...

A convolution is a mapping C of the set Z + of positive integers into the set P(Z +) of all subsets of Z + such that,for any n ∈ Z +, each member of C(n) is a divisor of n. If D(n) is the set of all divisors of n, for any ...

Nowadays, we witness changing trends in terms of the interest in language learning. In Poland, more and more higher education establishments, not only public, but also private, introduce various types of majors concerning ...

В умовах сучасності особливої актуальності набуває соціальне замовлення на підготовку усних перекладачів в рамках мовної освіти, яка забезпечувала б досягнення поставлених завдань в мінімальні терміни з найменшою витратою ...

In this paper we prove that the group (Zp) 2 × Zq ×Zr is CI-group, where p, q, r are primes such that q and r divide p − 1, and r divides q − 1.
• (2019)
Modular data are commonly studied in mathe- matics and physics. A modular datum defines a finite-dimensional representation of the modular group SL2(Z). In this paper, we show that there is a one-to-one correspondence ...
• (Луганский национальный университет им. Т. Шевченко, 2004)
In this paper the well-known connection between hyperidentities of an algebra and identities satisfied by the clone of this algebra is studied in a restricted setting, that of n-ary full hyperidentities and identities of ...
• (ДЗ "ЛНУ імені Тараса Шевченка", 2018)
In the present work the relations between the closure operators of two module categories are investigated in the case when the given categories are connected by two covariant adjoint functors H : R-Mod −→ S-Mod and T : ...

We accomplish the classification of Cohen–Macaulay modules over the curve singularities of type T44 and the description of the corresponding matrix factorizations, started in.
• (ДЗ"ЛНУ імені Тараса Шевченко", 2017)
We construct a simplified resolution for the trivial G-module Z, where G is a finite abelian group, and compare it with the standard resolution. We use it to calculate cohomologies of irreducible G-lattices and their duals.

Let X be a set of cardinality k, F be a family of subsets of X. We say that a cardinal , < k, is a color-detector of the hypergraph H = (X,F) if card (X) for every coloring : X ! k such that card (F) for ...

Let p, q > 2 be relatively prime integers and let Hp,q be the generalized Hecke group associated to p and q. The generalized Hecke group Hp,q is generated by X(z) = −(z − λp)−1 and Y (z) = −(z + λq) −1 where λp = 2 cos ...
