Abstract

In this paper, the concept of closed fuzzy pre-matroids is generalized to L-fuzzy set theory when L is a complete lattice. It is also called an L-fuzzifying matroid. In the definition of L-fuzzifying matroids, each subset can be regarded as an independent set to some degree. When L is completely distributive, an L-fuzzifying matroid can be characterized by means of its L-fuzzifying rank function. An L-fuzzifying matroid and its L-fuzzifying rank function are one-to-one corresponding.

      Matroids proposed by Whitney [33] are very important algebraic structures that generalize linear independence in vector spaces. Up to now, matroids have been widely investigated from the aspects of fuzzifying matroids [24,37], finite complexes and finitary matroids [3,4]. Besides, matroids have been interrelated to rough set theory.

      Throughout this article, L is always assumed to be a continuous lattice. The notions and some basic properties of L-closure systems and L-closure operators can be found in many publications (e.g., [4,5,19,21,31]). [2,3,19,21]

      It is known that matroids with no loops can be viewed as a special class of finite convexity spaces [6]. Inspired by this fact and the studies of M-fuzzifying matroids [28,29], Shi and Xiu proposed a new approach to the fuzzification of convexity spaces from a different perspective [30], which led to the notion of an M-fuzzifying convexity space (see Definition 2.2). An M-fuzzifying convexity on a set X is an M-fuzzy set on its power set with certain properties, and hence each subset of X can be regarded as a convex set to some degree.
