Abstract

In this paper, by using operations, some characterizations andsome properties of fuzzy lower and upper continuous multifunctionsand its weaker and stronger forms including fuzzy lower and upperweakly continuous, fuzzy lower and upper theta -continuous,fuzzy lower and upper strongly theta -continuous, fuzzy lowerand upper almost strongly theta -continuous, fuzzy lower andupper weakly theta -continuous, fuzzy lower and upper almostcontinuous, fuzzy lower and upper super continuous, fuzzy lowerand upper delta -continuous, are presented.
