Rings of functions on non-abelian groups

Maxson, C.J. (Algebra and Discrete Mathematics, 2009)

For several classes of finite nonabelian groups we investigate the structure of the ring of functions, R(C), determined by the cover C of maximal abelian subgroups. We determine the Jacobson radical J(R(C)) and the semisimple ...
Some classes of directoid groups

Gardner, B.J.; Parmenter, M.M. (Algebra and Discrete Mathematics, 2009)

Directoid groups are 2-torsion-free abelian groups with an extra binary operation assigning upper bounds. They thus constitute a generalization of abelian l-groups and an equational substitute for directed abelian groups. ...
Tiled orders of width 3

Zhuravlev, V.; Zhuravlyov, D. (Algebra and Discrete Mathematics, 2009)

We consider projective cover over tiled order and calculate the kernel of epimorphism from direct sum of submodules of distributive module to their sum.
Weak comultiplication modules over a pullback of commutative local Dedekind domains

Reza Ebrahimi Atani; Shahabaddin Ebrahimi Atani (Algebra and Discrete Mathematics, 2009)

The goal point of recent attempts to classify indecomposable modules over non-artinian rings has been pullback rings. The purpose of this paper is to outline a new approach to the classification of indecomposable weak ...
