FIXED POINT RESULTS ON A NONSYMMETRIC G- METRIC SPACES

We prove some xed point results for mappings that satisfy certain contractive conditions on a nonsymmetric complete G-metric space. Moreover, we prove the uniqueness of these xed point results.

CHARACTERIZATIONS OF NEARLY LINDEL¨OF SPACES

A topological space (X; ¿ ) is said to be nearly Lindel¨of if every regular open cover of (X; ¿ ) admits a countable subcover. In this paper, we obtain new characterizations and preservation theorems of nearly Lindel¨of spaces.

APPROXIMATE SOLUTIONS TO NONLINEAR PARTIAL INTEGRO-DIFFERENTIAL EQUATIONS WITH APPLICATIONS IN HEAT FLOW

In this paper, two different methods based on variational iteration method (VIM) and on differential transform method (DTM) are developed to approximate solutions of some partial integro-differential equations with applications in heat flow.

REMOTAL SETS IN THE SPACE OF P-INTEGRABLE FUNCTIONS

Let X be a Banach space and G be a closed bounded subset of X: For x 2 X; we set ½ (x;G) = sup fkx ¡ yk : y 2 Gg : The set G is called remotal if for any x 2 X; there exists g 2 G such that ½ (x;G) = kx ¡ gk : In this paper we show that for a separable remotal set G ½ X, the set of p-Bochner integrable functions, Lp(I;G) is in remotal Lp(I;X): Some other results are presented.

ON THE DIAMETER OF ZERO-DIVISOR GRAPHS OF IDEALIZATIONS WITH RESPECT TO INTEGRAL DOMAIN

Let R be a ring with unity and let M be an R - module. Let R(+)M be the idealization of the ring R by the R - module M. In this paper, we give new results on the diameter of ¡(R(+)M) when R is an integral domain.
