Abstract

This paper presents new classes of multifunctions called upper nearly $(\tau_1,\tau_2)$-continuous
multifunctions and lower nearly $(\tau_1,\tau_2)$-continuous multifunctions. Furthermore, some
characterizations of upper nearly $(\tau_1,\tau_2)$-continuous multifunctions and lower
nearly $(\tau_1,\tau_2)$-continuous multifunctions are established.
