Abstract

This article presents new classes of multifunctions called upper weakly $s$-$(\tau_1,\tau_2)$-continuous
multifunctions and lower weakly $s$-$(\tau_1,\tau_2)$-continuous multifunctions. Furthermore,
several characterizations of upper weakly $s$-$(\tau_1,\tau_2)$-continuous multifunctions and
lower weakly $s$-$(\tau_1,\tau_2)$-continuous multifunctions are discussed.
