Abstract

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