Almost Continuity for Multifunctions Defined from an Ideal Topological Space into a Bitopological Space

This paper presents new concepts of continuous multifunctions defined between an ideal topological space and a bitopological space, namely upper almost τ⁽σ₁,σ₂)-continuous multifunctions and lower almost τ⁽σ₁,σ₂)-continuous multifunctions. Moreover, several characterizations and some properties concerning upper almost τ⁽σ₁,σ₂)-continuousmultifunctions and lower almost τ⁽σ₁,σ₂)-continuous multifunctions are considered. Furthermore, the relationships between τ⁽σ₁,σ₂)-continuity and almost τ⁽σ₁,σ₂)-continuity are discussed.
