A New Weaker form of contra-continuit
Keywords:
Contra g-continuity, contra g#-continuity, g#-connected space
Abstract
The main results of this paper are several properties concerning contra g#-continuous maps. Furthermore, the relationships between the contra g#-continuity and some topological maps as well as Separation axioms are investigated.
