  • Quasi-duo Partial skew polynomial rings 
    Cortes, W.; Ferrero, M.; Gobbi, L. (Algebra and Discrete Mathematics, 2011)
    In this paper we consider rings R with a partial action α of Z on R. We give necessary and sufficient conditions for partial skew polynomial rings and partial skew Laurent polynomial rings to be quasi-duo rings and in this ...
  • On a semigroup of closed connected partial homeomorphisms of the unit interval with a fixed point 
    Chuchman, I. (Algebra and Discrete Mathematics, 2011)
    In this paper we study the semigroup IC(I,[a]) (IO(I,[a])) of closed (open) connected partial homeomorphisms of the unit interval I with a fixed point a∈I. We describe left and right ideals of IC(I,[0]) and the Green's ...
  • Minimax isomorphism algorithm and primitive posets 
    Bondarenko, V.M. (Algebra and Discrete Mathematics, 2011)
    The notion of minimax equivalence of posets, and a close notion of minimax isomorphism, introduced by the author are widely used in the study of quadratic Tits forms (in particular, for the description of P-critical ...
  • On Pseudo-valuation rings and their extensions 
    Bhat, V.K. (Algebra and Discrete Mathematics, 2011)
    Let R be a commutative Noetherian Q-algebra (Q is the field of rational numbers). Let σ be an automorphism of R and δ a σ-derivation of R. We define a δ-divided ring and prove the following: (1)If R is a pseudo-valuation ...
  • Generalized multiplicative bases for one-sided bimodule problems 
    Babych, V.; Golovashchuk, N.; Ovsienko, S. (Algebra and Discrete Mathematics, 2011)
    We consider a class of normal bimodule problems satisfying some structure, triangularity and finiteness conditions. For a bimodule problem from this class we construct explicitly an analogue of multiplicative basis which ...
  • Monic divisors of polynomial matrices over infinite field 
    Romaniv, A. (Algebra and Discrete Mathematics, 2011)
    The necessary and sufficient conditions of existence of monic divisors of a nonsingular polynomial matrix over an infinite field are established.
  • Fully invariant subgroups of an infinitely iterated wreath product 
    Leshchenko, Y.L. (Algebra and Discrete Mathematics, 2011)
    The article deals with the infinitely iterated wreath product of cyclic groups Cp of prime order p. We consider a generalized infinite wreath product as a direct limit of a sequence of finite nth wreath powers of Cp with ...
  • Free normal dibands 
    Zhuchok, A.V. (Algebra and Discrete Mathematics, 2011)
    We construct a free normal diband, a free (ℓn,n)-diband, a free (n,rn)-diband and a free (ℓn,rn)-diband. We also describe the structure of free normal dibands and characterize some least congruences on these dibands.
  • On the one-side equivalence of matrices with given canonical diagonal form 
    Shchedryk, V. (Algebra and Discrete Mathematics, 2011)
    The simpler form of a matrix with canonical diagonal form diag(1,…,1,φ,…,φ) obtained by the one-side transformation is determined.
  • Length of the inverse symmetric semigroup 
    Ganyushkin, O.; Livinsky, I. (Algebra and Discrete Mathematics, 2011)
    The length of the lattice of subsemigroups of the inverse symmetric semigroup ISn is calculated.
  • Generalized symmetric rings 
    Kafkas, G.; Ungor, B.; Halicioglu, S.; Harmanci, A. (Algebra and Discrete Mathematics, 2011)
    In this paper, we introduce a class of rings which is a generalization of symmetric rings. Let R be a ring with identity. A ring R is called central symmetric if for any a, b,c∈R, abc=0 implies bac belongs to the center ...
