  • Characterization of finite simple semigroup digraphs 
    Meksawang, J.; Panma, S.; Knauer, U. (Algebra and Discrete Mathematics, 2011)
    This paper characterizes directed graphs which are Cayley graphs of finite simple semigroups, i.e. of a subspecies of completely regular semigroups. Moreover we investigate the structure of Cayley graphs of finite simple ...
  • Derivations and relation modules for inverse semigroups 
    Gilbert, N.D. (Algebra and Discrete Mathematics, 2011)
    We define the derivation module for a homomorphism of inverse semigroups, generalizing a construction for groups due to Crowell. For a presentation map from a free inverse semigroup, we can then define its relation module ...
  • Diagonalizability theorem for matrices over certain domains 
    Zabavsky, B.; Domsha, O. (Algebra and Discrete Mathematics, 2011)
    It is proved that R is a commutative adequate domain, then R is the domain of stable range 1 in localization in multiplicative closed set which corresponds s-torsion in the sense of Komarnitskii.
  • Free field realizations of certain modules for affine Lie algebra slˆ(n,C) 
    Martins, R.A. (Algebra and Discrete Mathematics, 2011)
    For the affine Lie algebra slˆ(n,C) we study a realization in terms of infinite sums of partial differential operators of a family of representations introduced in [BBFK]. These representations generalize a construction ...
  • Graded limits of minimal affinizations and beyond: the multiplicity free case for type E₆ 
    Moura, A.; Pereira, F. (Algebra and Discrete Mathematics, 2011)
    e obtain a graded character formula for certain graded modules for the current algebra over a simple Lie algebra of type E₆. For certain values of their highest weight, these modules were conjectured to be isomorphic to ...
  • H -supplemented modules with respect to a preradical 
    Yahya Talebi; A. R. Moniri Hamzekolaei; Derya Keskin Tutuncu (Algebra and Discrete Mathematics, 2011)
    Let M be a right R-module and τ a preradical. We call M τ-H-supplemented if for every submodule A of M there exists a direct summand D of M such that (A+D)/D⊆τ(M/D) and (A+D)/A⊆τ(M/A). Let τ be a cohereditary preradical. ...
  • The influence of weakly s-permutably embedded subgroups on the p-nilpotency of finite groups 
    Changwen Li (Algebra and Discrete Mathematics, 2011)
    The research was partly supported by the NSF of China (grant no. 11071229) andthe NSF of the Jiangsu Higher Education Institutions (grant no. 10KJD110004).
