In this paper for the first time two new notions in fuzzy graphs viz., vertex-edge matrix (v-e matrix) of a fuzzy graph and
dominant fuzzy graph graphs are introduced. Several properties enjoyed by them are enumerated. Some interesting results in this direction is obtained.

This paper defines the notion of special elements like Smarandache zero divisors, Smarandache units, Smarandache
idempotents and Smarandache nilpotnents for semigroups. This is the first time such study has been carried out on semigroups

In this paper we study semigroup semirings using chain lattices as semirings. Such study is new and innovative. Condition for these semigroup semirings to contain special elements like zero divisors, units and idempotents are obtained.

In this paper we introduce a new class of closed maps namely 0g s-closed maps also introduce a new class of homeomorphisms called 0g s*-homeomorphisms. Further we show that the set of all 0g s*- homeomorphisms form a group under the operation composition of maps.

The aim of this paper is to introduce and study the concepts ofcontra g-closed and almost contra g-closed mappings and the interrelationship between other contra-closed maps
