On almost continuous and weakly continuous fuzzy multifunctions
The authors introduce the concept of fuzzy multifunction, by defining the concepts of its lower inverse and lower semi-continuity in terms of the notion of Q-coincidence. Subsequently several characterizing theorems for lower and upper almost continuous and weakly continuous fuzzy multifunctions are proved; the authors introduce fuzzy graph multifunction for this purpose and finally make a comparative study of different types of fuzzy multifunctions by examples.
