Abstract

We introduce two new types of multifunctions, namely upper (lower) $\theta $p$-$continuous multifunctions, between topological spaces. Besides characterising these multifunctions, we study some properties of upper $\theta $p$-$continuous multifunctions.

Keywords

Pre-$\theta $-open sets, strongly $\theta $-precontinuity, multifunction
