Abstract

This paper introduces new concepts of continuous multifunctions defined between a generalized
topological space and a bitopological space, namely upper almost $\mu(\sigma_1,\sigma_2)$-continuous
multifunctions and lower almost $\mu(\sigma_1,\sigma_2)$-continuous multifunctions. Moreover, several
characterizations and some properties concerning upper almost $\mu(\sigma_1,\sigma_2)$-continuous
multifunctions and lower almost $\mu(\sigma_1,\sigma_2)$-continuous multifunctions are investigated.
Furthermore, the relationships between $\mu(\sigma_1,\sigma_2)$-continuity and almost
$\mu(\sigma_1,\sigma_2)$-continuity are considered.
