The object of this paper is to study the locally projective and locally injective
modules. Specifically, this paper is a continuation of study of locally projective
and locally injective modules, where a new description of locally projective and
locally injective modules is obtained.
The object of this paper is to study the total as substructure of hom (M,N) R
for any two modules R M and R N , one of interesting question, is when the total
of a module N equals the hom (N, J (N)) R .
The object of this paper is to study the endomorphism rings of locally
projective and locally injective modules. Specifically, this paper is a continuation
of study of endomorphism rings of locally projective and locally injective modules
to be semipotent rings.
Let M and N be two modules over a ring R. The object of this paper is the study
of substructures of hom (M, N) R such as, radical, the singular, and co-singular
ideal and the total. The new obtained results include necessary and sufficient
conditi
ons the total of a ring R to equal some ideal of R.
In this paper we study the relationship between the maximal (prime)
elements of M and the maximal (prime) elements of L. We show that, if L is a
local lattice and the greatest element of M is weak principal, then M is local .
Then we define the Ja
cobson radical of M and denote it by J(M) and
we study its relationship with the Jacobson radical of L (J(L)) .
Afterwards, we define the semiprime element in a lattice module M, and we
show that the definitions of prime element and semiprime element are
equivalent when the greatest element of M is multiplication and we study the
properties equivalent to the properties of prime element in lattice module .
In this paper, we studied the concept of semi-potency of
endomorphism ring of modules. In addition to that, it has been
studied the endomorphism ring of semi injective ( projective)
modules and direct injective ( projective) modules.
