In this paper, we establish a new common fixed degree theorem for a sequence of fuzzy mappings in Menger PM-spaces. As an immediate consequence of this theorem, we obtain an improvement of a corresponding result of Chang et al. (Fuzzy Sets and Systems 87 (1997) 325–334). In addition, we also obtain some fixed degree and fixed point theorems for fuzzy mappings in fuzzy metric spaces. Our results unify and generalize the results of Heilpern (J. Math. Anal. Appl. 83 (1981) 566–569), Butnariu… CONTINUE READING
