On ultra multi functions in Bitopological spaces

2008

An almost nearly continuity and almost nearly quasi- continuity have been investigated in a bitopological case. Several prop- erties of almost upper (lower) nearly quasi-continuous and almost nearly quasi-continuous multifunctions have been obtained.

The paper deals with upper and lower quasi-continuity of multifunctions defined on a bitopological space. The main objective is to determine the conditions under which a multifunction is semi-continuous on a residual set.

Abstract. In this paper, we introduce and define a new class of sets, called Sı-open sets, in bitopological spaces. By using this set, we introduce and define the notion of Sı-continuity and investigate some of its properties. In particular, Sı-open sets and Sı-continuity are used to extend some known results of continuity.
