On Minimal and Maximal T1 –space Via Β*c-open set

Abstract

            In this paper, we introduced study about properties of the spaces minimal T₁ – Space and maximal T₁ – space by using the set open (respace β - open, Β^*c– open) sets and we concluded some propositions, remarks and relations between spaces m Β^*c – T₁ space and M Β^*c – T₁ space and study the relation between m – space and M – space to space T₁ – space. Where we find every m Β^*c – T₁ space is M Β^*c – T₁ space, but the converse is not true in general. Also we introduced hereditary properties and topological properties.
