Abstract

In this paper, we redefine the concepts of join spaces and product spaces of $M$-fuzzifying convex spaces. Then we further investigate the $S_i$ ($i=0,1,2$) separated degrees of an $M$-fuzzifying convex space in a logical viewpoint. Finally, we study the $S_i$ ($i=0,1,2$) separated degrees of an $M$-fuzzifying convex space from the aspect of convergence structures.
