Abstract

In this paper, we introduce the notions of upper weakly \alpha(\tau_1,\tau_2)\sigma^\star-continuous multifunctions and lower weakly \alpha(\tau_1,\tau_2)\sigma^\star-continuous multifunctions. Moreover, we investigate some characterizations of upper weakly \alpha(\tau_1,\tau_2)\sigma^\star-continuous multifunctions and lower weakly \alpha(\tau_1,\tau_2)\sigma^\star-continuous multifunctions.
