Goldie-Rad-Supplemented Modules
(Ovidius Univ Press, 2014)In this paper we introduce beta** relation on the lattice of submodules of a module M. We say that submodules X, Y of M are beta** equivalent, X beta**Y, if and only if X+Y/X subset of Rad(M)+X/X and X+Y/Y subset of ... -
Modules Which Are Self-P-Injective Relative To Projection Invariant Submodules
(Ovidius Univ Press, 2017)In this article, we focus on modules M such that every homomorphism from a projection invariant submodule of M to M can be lifted to M. Although such modules share some of the properties of PI-extending (i.e., every ... -
On Rad-D-12 Modules
(Ovidius Univ Press, 2013)Let M be a right R-module. We call M Rad-D-12, if for every submodule N of M, there exist a direct summand K of M and an epimorphism alpha : K -> M/N such that Ker alpha subset of Rad(K). We show that a direct summand of ... -
Some New Types Of Associated Curves In Euclidean 3-Space
(Ovidius Univ Press, 2018)In this paper, we introduce the concept of D-direction curve and C-direction curve of a given curve using the alternative frame {N, C, W} in Euclidean 3-space. Furthermore, we define a (N, C) plane curve, a (N, W) plane ...
