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