  • Combinatorics of partial wreath power of finite inverse symmetric semigroup ISd 
    Kochubinska, Y. (Algebra and Discrete Mathematics, 2007)
    We study some combinatorial properties of ≀ k pISd. In particular, we calculate its order, the number of idempotents and the number of D-classes. For a given based graph Γ ⊂ T we compute the number of elements in its ...
  • Natural dualities for varieties generated by a set of subalgebras of a semi-primal algebra 
    Mathonet, P.; Niederkorn, P.; Teheux, B. (Algebra and Discrete Mathematics, 2007)
    The main contribution of this paper is the construction of a strong duality for the varieties generated by a set of subalgebras of a semi-primal algebra. We also obtain an axiomatization of the objects of the dual category ...
  • On classification of CM modules over hypersurface singularities 
    Bondarenko, V.V. (Algebra and Discrete Mathematics, 2007)
    This article is devoted to a special case of classification problem for Cohen-Macaulay modules over hypersurface singularities.
  • On division rings with general involution 
    Idris, I.M. (Algebra and Discrete Mathematics, 2007)
    In this work we consider division rings with general involution. Properties of such division rings are investigated. General valuation of such division rings is introduced. We extend to this general notion some result ...
  • On Frobenius full matrix algebras with structure systems 
    Fujita, H.; Sakai, Y.; Simson, D. (Algebra and Discrete Mathematics, 2007)
    Let n ≥ 2 be an integer. In [5] and [6], an n × n A-full matrix algebra over a field K is defined to be the set Mn(K) of all square n × n matrices with coefficients in K equipped with a multiplication defined by a ...
  • On H-closed topological semigroups and semilattices 
    Chuchman, I.; Gutik, O. (Algebra and Discrete Mathematics, 2007)
    In this paper, we show that if S is an H-closed topological semigroup and e is an idempotent of S, then eSe is an H-closed topological semigroup. We give sufficient conditions on a linearly ordered topological semilattice ...
  • R-S correspondence for the Hyper-octahedral group of type Bn - A different approach 
    Parvathi, M.; Sivakumar, B.; Tamilselvi, A. (Algebra and Discrete Mathematics, 2007)
    In this paper we develop a Robinson Schensted algorithm for the hyperoctahedral group of type Bn on partitions of ( 1 2 r(r + 1) + 2n) whose 2−core is δr, r ≥ 0 where δr is the partition with parts (r, r−1, . . . , ...
  • Theory of paradeterminants and its applications 
    Zatorsky, R.A. (Algebra and Discrete Mathematics, 2007)
    We consider elements of linear algebra based on triangular tables with entries in some number field and their functions, analogical to the classical notions of a matrix, determinant and permanent. Some properties are ...
  • The structure of automorphism groups of semigroup inflations 
    Kudryavtseva, G. (Algebra and Discrete Mathematics, 2007)
    In this paper we prove that the automorphism group of a semigroup being an inflation of its proper subsemigroup decomposes into a semidirect product of two groups one of which is a direct sum of full symmetric groups.
