Congruences on Inverse Semigroups using Kernel Normal System

Laila M.Tunsi

Congruences on inverse semigroups via the (kernel-trace) method introduced by Scheiblich in 1974. In this paper we discuss the congruences on inverse semigroups by using the technique of Kernel normal systems. Congrueneses on inverse semigroup were described in terms of congruences pairs (ker tr ). It ...

Periodic solutions for nonlinear systems of multiple integro-integral differential equations of (V F) and (F V) type with isolated singular kernels

Raad N. Butris , Hewa Selman Faris

In this paper, the numerical-analytic method has been used to study the existence and approximation of the periodic solutions for the vector T-system of new nonlinear multiple integro-differential equations of mixed (Volterra-Fredholm) and (Fredholm-Volterra) types. Our main task provided sufficient ...

Soft Pre Separation Axioms and Function with Soft Pre Closed Graph

Nehmat K. Ahmed , Alias B. Khalaf

Several notions on soft topology are studied and their basic properties are investigated by using the concept of soft pre open sets and soft pre closure operator which are derived from the basics of soft set theory established by Molodtsov [1]. In this paper we introduce some soft separation axioms ...
