“…There is a lot of discussion about the fuzzy operators located outside Zadeh operators [3,4,5,6,7] , but there is little discussion about the fuzzy operators located within Zadeh operators. The article [1] first constructed fuzzy zero operators located within Zadeh operators and constructed fuzzy Q operators located within Zadeh operators and proved that fuzzy zero operators are the boundary operator located within Zadeh operators and fuzzy Q operators are a new class of continuous fuzzy operators located within Zadeh operators. By analyzing relation between Zadeh operator and three common generalized operators (probability operators, Boundary operators and infinite operators), this paper discussed membership relation in Zadeh operator and three generalized operator in common use, and constructed fuzzy K operators located within Zadeh operators and zero operators.…”
