Abstract

In this paper, we introduce a new Kupka type function called Î»-Kupka and we investigate some of its properties. Also we obtain several characterizations and some basic properties concerning upper (lower) Î»-continuous multifunctions.

Keywords

Topological spaces , Î›-sets , Î»-open sets , Î»-closed sets , Î»-Kupka continuity , multifunction
