Abstract ON CERTAIN CLASSES OF MODULES
"... Let X be any class of Rmodules containing 0 and closed under isornorpllic images. With any such X we associate three classes FX, FX and ¿5X. 7.'lie study of some of the closure properties of three classes allows Lis to obtain characterization of Artinian modules dualizing results of Chatters. ..."

ON CERTAIN CLASSES OF ANALYTIC FUNCTIONS
, 2005
"... ABSTRACT. Let A be the class of functions f: f(z) = z + ∑ ∞ n=2 anz n which are analytic in the unit disk E. We introduce the class Bk(λ, α, ρ) ⊂ A and study some of their interesting properties such as inclusion results and covering theorem. We also consider an integral operator for these classes ..."

DIFFERENTIALS IN CERTAIN CLASSES OF GRAPHS
"... Abstract. Let X ⊂ V be a set of vertices in a graph G = (V, E). The boundary B(X) of X is defined to be the set of vertices in V − X dominated by vertices in X, that is, B(X) = (V − X) ∩ N(X). The differential ∂(X) of X equals the value ∂(X) = B(X)  − X. The differential of a graph G is defi ..."

is defined as ∂(G) = max{∂(X)X ⊂ V}. It is easy to see that for any graph G having vertices of maximum degree ∆(G), ∂(G) ≥ ∆(G)−1. In this paper we characterize the classes of unicyclic graphs, split graphs, grid graphs, kregular graphs, for k ≤ 4, and bipartite graphs for which ∂(G) = ∆(G) − 1. We also
On The Zeros of Certain Class of Polynomials
"... Abstract: Let P(z) be a polynomial of degree n with real or complex coefficients. The aim of this paper is to obtain a ring shaped region containing all the zeros of P(z). Our results not only generalize some known results but also a variety of interesting results can be deduced from them. I. Introd ..."

Abstract: Let P(z) be a polynomial of degree n with real or complex coefficients. The aim of this paper is to obtain a ring shaped region containing all the zeros of P(z). Our results not only generalize some known results but also a variety of interesting results can be deduced from them. I. Introduction and Statement of Results The following beautiful result which is wellknown in the theory of distribution of zeros of polynomials is due to Enestrom and Kakeya [9].
