Abstract:

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