Abstract:

A new class of multifunctions, called upper (lower) 𠛽 ( 𠜇 𠑋 , 𠜇 𠑌 ) -continuous multifunctions, has been defined and studied. Some characterizations and several properties concerning upper (lower) 𠛽 ( 𠜇 𠑋 , 𠜇 𠑌 ) -continuous multifunctions are obtained. The relationships between upper (lower) 𠛽 ( 𠜇 𠑋 , 𠜇 𠑌 ) -continuous multifunctions and some known concepts are also discussed.
