  • Variety of Jordan algebras in small dimensions 
    Kashuba, I. (Algebra and Discrete Mathematics, 2006)
    The variety J orn of Jordan unitary algebra structures on k n , k an algebraically closed field with char k 6= 2 , is studied, as well as infinitesimal deformations of Jordan algebras. Also we establish the list of ...
  • A construction of dual box 
    Ovsienko, S. (Algebra and Discrete Mathematics, 2006)
    Let R be a quasi-hereditary algebra, F(∆) and F(∇) its categories of good and cogood modules correspondingly. In [6] these categories were characterized as the categories of representations of some boxes A = A∆ and A∇. ...
  • Geometry monoid of the left distributivity and the left idempotency 
    Jedlicka, P. (Algebra and Discrete Mathematics, 2006)
    We construct here the geometry monoids of LDI (left distributive idempotent) and of LDLI (left distributive left idempotent) identities. We study their properties and construct a monoid with solvable word problem based ...
  • Fibrations and cofibrations in a stratified model category 
    Spalinski, J. (Algebra and Discrete Mathematics, 2006)
    We introduce n-acyclic cofibrations and n-acyclic fibrations in a stratified model category and show that they have the key properties of (acyclic) cofibrations and (acyclic) fibrations in a model category. We analyse ...
  • Lattices of topologies of algebraic systems 
    Arnautov, V.I.; Filippov, K.M. (Algebra and Discrete Mathematics, 2006)
    The article is based on the report, which was delivered on a plenary sitting on the 5th International Algebraic Conference in the Ukraine (Odessa, July, 2005) and is a survey of the results on the lattices of topologies ...
  • 5th International Algebraic Conference in Ukraine 
    Kirichenko, V.V.; Sushchansky, V.I.; Varbanets, P.D. (Algebra and Discrete Mathematics, 2006)
    This volume contains papers based on the talks presented at the 5t h In- ternational Algebraic Conference in Ukraine, which took place in Ode ssa on July 20–27, 2005. The conference was organized by Odessa I. I. ...
  • On automorphism groups of some modules 
    Dashkova, O.Yu. (Algebra and Discrete Mathematics, 2006)
    In this paper we investigated ZG-module A, where G is either nilpotent or soluble group of infinite special rank. It is described the construction of these modules in the case, if for any proper subgroup H of infinite ...
  • On the dimension of Kirichenko space 
    Plakhotnyk, M. (Algebra and Discrete Mathematics, 2006)
    We introduce a notion of the Kirichenko space which is connected with the notion of Gorenstein matrix (see [2], ch. 14). Every element of Kirichenko space is an n × n matrix, whose elements are solutions of the equations ...
  • Weighted partially orderd sets of finite type 
    Drozd-Koroleva, O. (Algebra and Discrete Mathematics, 2006)
    We define representations of weighted posets and construct for them reflection functors. Using this technique we prove that a weighted poset is of finite representation type if and only if its Tits form is weakly positive; ...
  • τ-complemented and τ-supplemented modules 
    Al-Takhman, K.; Lomp, C.; Wisbauer, R. (Algebra and Discrete Mathematics, 2006)
    Proper classes of monomorphisms and short exact sequences were introduced by Buchsbaum to study relative homological algebra. It was observed in abelian group theory that complement submodules induce a proper class of ...
  • Strongly orthogonal and uniformly orthogonal many-placed operations 
    Belyavskaya, G.; Mullen, G.L. (Algebra and Discrete Mathematics, 2006)
    In [3] we have studied connection between orthogonal hypercubes and many-placed (d-ary) operations, have considered different types of orthogonality and their relationships. In this article we continue study of orthogonality ...
  • On the growth of the identities of algebras 
    Giambruno, A.; Mishchenko, S.; Zaicev, M. (Algebra and Discrete Mathematics, 2006)
  • On finite posets of injinj-finite type and their Tits forms 
    Bondarenko, V.M.; Styopochkina, M.V. (Algebra and Discrete Mathematics, 2006)
    We prove one theorem on connection between inj-finiteness of a finite poset and positive definiteness of its Tits form.
  • Linear cellular automata: Garden of Eden Theorem, L-surjunctivity and group rings 
    Ceccherini-Silberstein, T.; Coornaert, M. (Algebra and Discrete Mathematics, 2006)
    This paper is a slightly extended version of the lecture given by the first author at the “5th International Algebraic Conference in Ukraine” held on July 20–27 2005 at the Odessa I.I. Mechnikov National University.
  • Modules over braces 
    Rump, W. (Algebra and Discrete Mathematics, 2006)
  • The generalized path algebras over standardly stratified algebras 
    Wang, S. (Algebra and Discrete Mathematics, 2006)
    In this note, it is proved that the generalized path algebras over standardly stratified algebras are also standardly stratified, and the generalized path algebras over quasi-hereditary algebras are also quasi-hereditary. ...
  • On minimal ω-composition non-H-formations 
    Belous, L.I.; Selkin, V.M. (Algebra and Discrete Mathematics, 2006)
    Let H be some class of groups. A formation F is called a minimal τ -closed ω-composition non-H-formation [1] if F * H but F1 ⊆ H for all proper τ -closed ω-composition subformations F₁ of F. In this paper we describe the ...
  • Value distribution of general Dirichlet series. VIII 
    Laurincikas, A. (Algebra and Discrete Mathematics, 2006)
    A joint limit theorem on the complex plane for a new class of general Dirichlet series is proved.
  • Pseudodiscrete balleans 
    Protasova, O.I. (Algebra and Discrete Mathematics, 2006)
    A ballean B is a set X endowed with some family of subsets of X which are called the balls. The properties of the balls are postulated in such a way that a ballean can be considered as an asymptotic counterpart of a ...
