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 ^ (₁, ₂) -continuous multifunctions and lower almost ^ (₁, ₂) -continuous multifunctions. Moreover, several characterizations and some properties concerning upper almost ^ (₁, ₂) -continuousmultifunctions and lower almost ^ (₁, ₂) -continuous multifunctions are considered. Furthermore, the relationships between ^ (₁, ₂) -continuity and almost ^ (₁, ₂) -continuity are discussed.
