The lower semi-continuity of a class of functions in nonsmooth critical point theory;

In the lower semi-continuity,this essay provide one plenty condition about a fuzzy sets is preinvex fuzzy sets,then proved it.

This approach fully used result: There is minimizer in fuzzy sets of lower semi-continuity ,but not the traditional way of to argue about the fuzzy convexity,it combined research of fuzzy convexity and the relation contents of traditional analysis as a unity.

The function is assumed to be lower semicontinuous and bounded from below throughout this papeer.

This paper shows that lower semicontinuous accretive and monotone operators T cannot be multivalued.
