摘要
本文是文[6]的继续,研究模糊保凸映射,用子基线段给出其特征定义1 设ψ是fts(x,J)的闭子基,非空模糊集c称为ψ-闭(或ψ-凸)如果有族■■ψ使得c=∩■。记H(X,ψ)是所有ψ-闭模糊集的全体。F-映射f:(X,J)→(Y,U)称为关于它们的闭子基ψ和ψ的F-保凸映射(简记F—cp映射)
The present paper is a continuation of investigations on subbase convexity theory, started in [6]. we are now concerned with so-called fuzzy convexty preserving (F—cp) mappings. A result is a characterization of F—cp maps in terms of subbasic line segments.
