  • Savchuk, Yuri (Луганский национальный университет им. Т. Шевченко, 2004)
    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.
  • Gusev, S. V.; Skokov, D.V.; Vernikov, B. M . (ДЗ "Луганський національний університет імені Тараса Шевченка", 2018)
    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 ...
  • Rump, Wolfgang (Луганский национальный университет им. Т. Шевченко, 2004)
    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 ...
  • Sagi, S. (2018)
    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 ...
  • Леонтьєва, І. В. (ДЗ "Луганський національний університет імені Тараса Шевченка", 2023)
    У статті розглянуто теоретичні та практичні аспекти ChatGPT як технології навчання у вищій школі здобувачів першого (бакалаврського) рівня вищої освіти. Зроблено стислий теоретичний огляд актуальних англомовних та ...
  • Banka, K. (ДЗ "Луганський національний університет" імені Тараса Шевченка, 2016)
    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 ...
  • Демченко, Н.О. (ДЗ "ЛНУ імені Тараса Шевченка", 2019)
    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 ...
  • Subbotin, I. Y. (ДЗ "ЛНУ імені Тараса Шевченка", 2019)
    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.
  • Singh, G. (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 ...
  • Denecke, Klaus; Jampachon, Prakit (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 ...
  • Kashu, A. I. (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 : ...
  • Drozd, Y. A.; Tovpyha, O. V. (ДЗ "ЛНУ імені Тараса Шевченка", 2019)
    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.
  • Drozd, Yu.; Plakosh, A. (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.
  • Protasov, I. V.; Protasova, O. I. (Луганский национальный университет им. Т. Шевченко, 2005)
    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 ...
  • Koruoğlu, Ö .; Meral, T.; Sahin, R. (ДЗ "ЛНУ імені Тараса Шевченка", 2019)
    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 ...
  • Bazyleu, Dzmitry F.; Tikhonov, Sergey V.; Yanchevski, Vyacheslav I. (Луганский национальный университет им. Т. Шевченко, 2003-11-28)
  • liynyk, A . O; Russyev, A . (2019)
    It is proved that conjugated periodic elements of the infinite wreath power of a finite permutation group are conjugated in the finite state wreath power of this group. Counterexamples for nonperiodic elements are given.
  • Brieussel, J.; Gournay, A. (ДЗ "ЛНУ імені Тараса Шевченка", 2018)
    We introduce the notion of connection thickness of spheres in a Cayley graph, related to dead-ends and their retreat depth. It was well-known that connection thickness is bounded for finitely presented one-ended groups. ...
  • Jakubíková -Studenovská, D.; Janičková, L. (ДЗ "ЛНУ імені Тараса Шевченка", 2018)
    For a monounary algebra A = (A, f) we study the lattice Quord A of all quasiorders of A, i.e., of all reflexive and transitive relations compatible with f. Monounary algebras (A, f) whose lattices of quasiorders are ...
  • Chernukh, D. (ДЗ "Луганський національний університет імені Тараса Шевченка", 2022)
    The problems of the development of the corporate culture of enterprises are becoming more and more relevant in modern business conditions. In this regard, the terminological apparatus regarding the essence and content of ...
