內(nèi)容摘要：
Convexity exists in many mathematical structures. By abstracting some basic properties of convex sets, (axiomatic, abstract) convex structures have been proposedand have been studied inthe framework of topology, algebra, order and so on.With the development of fuzzy set theory, different types of fuzzy convex structures have been introduced, includingL-convex structures, M-fuzzifying convex structures and(L,M)-fuzzy convex structures.This motivates us to consider the relationships between different types of fuzzy convex structures. This talk aims to establish the relationships between L-convex structures and L-fuzzifying convex structures from a categorical aspect.
In thistalk,the concepts of fuzzifying L-hull spaces and fuzzifyingL-convex spaces are introduced and the resulting categories are shown to be isomorphic to that of L-fuzzifying convex spaces. As applications of these concepts,it is shown that the category of L-fuzzifying convex spaces can be embedded inthe category of L-convex spaces as a simultaneously bireflective and bicoreflectivesubcategory.
