On Upper and Lower ๐ฝ(๐๐,๐๐)-Continuous Multifunctions
A new class of multifunctions, called upper (lower) ๐ฝ(๐๐,๐๐)-continuous multifunctions, has been defined and studied. Some characterizations and several properties concerning upper (lower) ๐ฝ(๐๐,๐๐)-continuous multifunctions are obtained. The relationships between upper (lower) ๐ฝ(๐๐,๐๐)-continuous mu...

| description | A new class of multifunctions, called upper (lower) ๐ฝ(๐๐,๐๐)-continuous multifunctions, has been defined and studied. Some characterizations and several properties concerning upper (lower) ๐ฝ(๐๐,๐๐)-continuous multifunctions are obtained. The relationships between upper (lower) ๐ฝ(๐๐,๐๐)-continuous multifunctions and some known concepts are also discussed. |
