Abstract

This paper presents new classes of multifunctions called upper weakly quasi (τ1, τ2)-continuous multifunctions and lower weakly quasi (τ1, τ2)-continuous multifunctions. Moreover, several characterizations and some properties concerning upper weakly quasi (τ1, τ2)-continuous multifunctions and lower weakly quasi (τ1, τ2)-continuous multifunctions are considered.
