bopen Sets In Topological Spaces

Abstract

This work consist of two sections. In section one we recall the
definition of connected sets. We also introduce similar definition using
b  open sets and study the property of this definition. In ]5[ ]1[ I  space
and MI  space are studied respectively. In section two we introduce
similar definition TB space
 using b  open sets. In particular we will
prove that in MI-space the TB space
 and T space D
 are equivalent.
