Strongly noncosingular modules
An R-module M is called strongly noncosingular if it has no nonzero Rad-small (cosingular) homomorphic image in the sense of Harada. It is proven that (1) an R-module M is strongly noncosingular if and only if M is coatomic and noncosingular; (2) a right perfect ring R is Artinian hereditary serial if and only if the class of injective modules coincides with the class of (strongly) noncosingula...
متن کاملStrongly cotop modules
In this paper, we introduce the dual notion of strongly top modules and study some of the basic properties of this class of modules.
متن کاملOn Gelfand-Zetlin modules over Uq(gln)
We construct and investigate a new large family of simple modules over U q (gl n).
متن کاملSTRONGLY DUO AND CO-MULTIPLICATION MODULES
Let R be a commutative ring. An R-module M is called co-multiplication provided that foreach submodule N of M there exists an ideal I of R such that N = (0 : I). In this paper weshow that co-multiplication modules are a generalization of strongly duo modules. Uniserialmodules of finite length and hence valuation Artinian rings are some distinguished classes ofco-multiplication rings. In additio...
متن کاملOn Gelfand-Zetlin modules over orthogonal Lie algebras
We construct a new family of simple modules over orthogonal complex Lie algebra associated with Gelfand-Zetlin formulae for simple nite dimensional modules and study the corresponding Gelfand-Zetlin subalgebra.
