*g - CLOSED SETS IN IDEAL TOPOLOGICAL SPACES

 

Characterizations and properties of I*g-closed sets and I*g-open sets are given. A characterization of normal spaces is given in terms of I*g-open sets.

Also, it is established that an I*g-closed subset of an I-compact space is I-compact.

A DECOMPOSITION OF () - CONTINUITY IN GENERALIZED TOPOLOGICAL SPACES

 

In this paper, we introduce and study the notions of ω(,λ) -H-continuity and ω*(,λ)-H-continuity in generalized topological spaces. Also, we prove that f: (X,) (Y,λ,H) is (,λ)-continuous if and only if it is ω(,λ)-H-continuous and ω*(,λ)- H-continuous.

ON α*-SETS AND A DECOMPOSITION THEOREM

 

We define a new family of sets in a space with a weak structure and give a decomposition of (ω,ώ) - continuity, a generalization of a decomposition of continuous functions.

EXISTENCE RESULTS FOR FRACTIONAL IMPULSIVE

INTEGRO-DIFFERENTIAL EQUATIONS WITH NONLOCAL

CONDITION

 

This paper is mainly concerned with the existence of solutions of impulsive fractional abstract integro-differential equations in Banach spaces. The results are obtained by using fixed point principles. An example is provided to illustrate the theory.

ON ALMOST WN - INJECTIVE RINGS

Let R be a ring. Let  MR be a module with S=End (MR). The module M is called almost Wnil-injective (briefly right AWN-injective ) if, for any 0≠aєN(R), there exists n1 and an S-submodule  Xa of M such that na0 and lm(rR(an)) = Man ΘXan as left S-modules .If RR is almost Wnil-injective , then we call R is right almost Wnil-injective ring . In this paper ,we give some characterization and properties of almost Wnil-injective rings .In particular , Conditions under which right almost Wnil-injective rings are n-regular rings and n-weakly regular rings are given .Also we study rings whose simple singular right R-module are almost Wnil-injective , It is proved that if R is a NCI ring ,MC2 , whose every simple singular R-module is almost Wnil-injective , Then R is reduced .
