  • A note to my paper “Multi-algebras from the viewpoint of algebraic logic” 
    Cırulis, Janis (Луганский национальный университет им. Т. Шевченко, 2003)
    The definition of a resolvent, introduced in the paper mentioned in the title, is simplified, and some misprints in that paper are corrected.
  • A note to our paper “Automorphisms of homogeneous symmetric groups and hierarchomorphisms of rooted trees” 
    Lavrenyuk, Yaroslav V.; Sushchansky, Vitaly I. (Луганский национальный университет им. Т. Шевченко, 2005)
    The results on automorphisms of homogeneous alternating groups are corrected and improved.
  • A Ramsey algebraic study of matrices 
    Teoh, Z .Y.; Teh, W.C. (ДЗ "ЛНУ імені Тараса Шевченка", 2019)
    The notion of a topological Ramsey space was introduced by Carlson some 30 years ago. Studying the topological Ramsey space of variable words, Carlson was able to derive many classical combinatorial results in a unifying ...
  • A random Bockstein operator 
    Zabka, M. (ДЗ "ЛНУ імені Тараса Шевченка", 2018)
    As more of topology’s tools become popular in analyzing high-dimensional data sets, the goal of understanding the underlying probabilistic properties of these tools becomes even more important. While much attention has ...
  • A survey article on some subgroup embeddings and local properties for soluble PST-groups 
    Beidleman, J. C. (2017)
    Let G be a group and p a prime number. G is said to be a Yp-group if whenever K is a p-subgroup of G then every subgroup of K is an S-permutable subgroup in NG(K). The group G is a soluble PST-group if and only if G is ...
  • A way of computing the Hilbert series 
    Haider, A. (ДЗ "ЛНУ імені Тараса Шевченка", 2018)
    Let S = K[x1, x2, . . . , xn] be a standard graded K-algebra for any field K. Without using any heavy tools of com- mutative algebra we compute the Hilbert series of graded S-module S/I, where I is a monomial ideal.
  • Abelian doppelsemigroups 
    Zhuchok, A.V.; Knauer, K. (ДЗ"ЛНУ імені Тараса Шевченко", 2018)
    A doppelsemigroup is an algebraic system consisting of a set with two binary associative operations satisfying certain identities. Doppelsemigroups are a generalization of semi-groups and they have relationships with such ...
  • Abnormal subgroups and Carter subgroups in some infinite groups 
    Kurdachenko, L. A.; Subbotin, I. Ya. (Луганский национальный университет им. Т. Шевченко, 2005)
    Some properties of abnormal subgroups in generalized soluble groups are considered. In particular, the transitivity of abnormality in metahypercentral groups is proven. Also it is proven that a subgroup H of a radical ...
  • Additivity of elementary maps on alternative rings B. L. M. Ferreira 
    Shestakov, I. P. (ДЗ "ЛНУ імені Тараса Шевченка", 2019)
    Let R and R′ be alternative rings. In this article we investigate the additivity of surjective elementary maps of R × R′ . As a main theorem, we prove that if R contains a non-trivial idempotent satisfying some conditions, ...

    Unknown author (Institute of Applied Mathematics and Mechanics of the National Academy of Sciences of Ukraine, 2002)
  • Algebra and Discrete Mathematics - № 1 - 2003 
    Unknown author (Луганский национальный университет им. Т. Шевченко, 2002-12-13)
  • Algebra and Discrete Mathematics - № 2 - 2003 
    Unknown author (Луганский национальный университет им. Т. Шевченко, 2003)
  • Algebraic Morse theory and homological perturbation theory 
    Sköldberg, E. (2018)
    We show that the main result of algebraic Morse theory can be obtained as a consequence of the perturbation lemma of Brown and Gugenheim.
  • Algebras and logics of partial quasiary predicates 
    Nikitchenko, M.; Shkilniak, S. (2017)
    In the paper we investigate algebras and logics defined for classes of partial quasiary predicates. Informally speaking, such predicates are partial predicates defined over partial states (partial assignments) of ...
  • Almost all derivative quivers of artinian biserial rings contain chains 
    Avdeeva, Tetjana; Ganyushkin, Olexandr (Луганский национальный университет им. Т. Шевченко, 2002-12-06)
  • An additive divisor problem in Z[i] 
    Savasrtu, O. V.; Varbanets, P. D. (Луганский национальный университет им. Т. Шевченко, 2003-02-22)
  • An algebraic version of the Strong Black Box 
    Göbel, Rüdiger; Wallutis, Simone L. (Луганский национальный университет им. Т. Шевченко, 2003-05-23)
  • Automorphism groups of superextensions of finite monogenic semigroups 
    Banakh, T.; Gavrylkiv, V. (2019)
    A family L of subsets of a set X is called linked if A ∩ B 6= ∅ for any A, B ∈ L. A linked family M of subsets of X is maximal linked if M coincides with each linked family L on X that contains M. The superextension ...
  • Automorphisms of homogeneous symmetric groups and hierarchomorphisms of rooted trees 
    Lavrenyuk, Yaroslav V.; Sushchansky, Vitalii I. (Луганский национальный университет им. Т. Шевченко, 2003)
  • Automorphisms of the endomorphism semigroup of a free abelian diband 
    Zhuchok, Yu. V. (ДЗ "Луганський національний університет імені Тараса Шевченка", 2018)
    We determine all isomorphisms between the endomorphism semigroups of free abelian dibands and prove that all automorphisms of the endomorphism semigroup of a free abelian diband are inner.
