Abstract

A new class of continuous multifunctions between a generalized topological space and a bitopological
space, namely upper (lower) weakly $\mu(\sigma_1,\sigma_2)$-continuous multifunctions, has been
defined and studied. Moreover, several characterizations and some properties concerning upper weakly
$\mu(\sigma_1,\sigma_2)$-continuous multifunctions and lower weakly $\mu(\sigma_1,\sigma_2)$-continuous
multifunctions are established. Furthermore, the relationships between almost
$\mu(\sigma_1,\sigma_2)$-continuity and weak $\mu(\sigma_1,\sigma_2)$-continuity are considered.
