摘要:
LetFM12be the group algebra of the Mathieu groupM12over an algebraically closed field of characteristic 3. Then the Loewy and socle series of the Green correspondents of all simple (irreducible)FM12-modules with respect to the normalizers of their vertices are determined without using computers.

摘要:
In this paper we study Lie superalgebras g with a non-degenerate super-symmetric, consistentg-invariant bilinear formB. Such a (g,B) is called quadratic Lie superalgebra.

摘要:
A ringRis called left FGF (resp. CF) if every finitely generated (resp. cyclic) leftR-module embeds in a free module. In this paper we give new partial affirmative answers to two open problems in the area of Module and Ring Theory, the so-called FGF problem: Is a left FGF ring Quasi-Frobenius? and the CF problem: Is a left CF ring left artinian?.

摘要:
We prove that an integral domain with a direct topology is is algebraically closed in its completion and that a direct topology on a field can be extended to a direct topology on a simple algebraic extension. We give a canonical description of the inverse of an element in the completion of a ring with a direct topology. We consider a ring topology constructed by Marcos in terms of direct topologies and give generalizations of two constructions of Mutylin.
