Some results on maximal open sets

In this paper, the notion of maximal m-open set is introduced and itsproperties are investigated. Some results about existence of maximal m-open setsare given. Moreover, the relations between maximal m-open sets in an m-spaceand maximal open sets in the corresponding generated topology are considered.Our results are supported by examples and counterexamples.

Some points on generalized open sets

The paper is an attempt to represent a study of limit points, boundary points, exterior points, border, interior points and closure points in the common generalized topological space. This paper takes a look at the possibilities of an extended topological space and it also considers the new characterizations of dense set.

Some Remarks on Connected Sets

This note will consist of a few disconnected remarks on connected sets . i. Swingle2 raised the question whether the plane is the sum of c disjoint biconnected sets . The answer as we shall show is affirmative . First we construct a biconnected set A with a dispersion point x such that any two points of A -x can be separated . (The first such set was constructed by Wilder.-' Our construction wi...
