In this paper, we introduce axiomatic notions of both L-convex bases and L-convex subbase and discuss their relations with L-convex spaces.

It is shown that the category of concave L-convergence spaces and that of L-concave spaces are isomorphic and the category of preconcave L-convergence spaces ...

Adopting the terminology of fuzzy topology, both of fuzzy convexity spaces in the sense of Rosa and Maruyama are called L-convex structures nowadays. In the ...

Abstract. This paper is to characterize L-concavities and L-convexities via some derived forms of relations and operators.

In mathematics, the L p spaces are function spaces defined using a natural generalization of the p-norm for finite-dimensional vector spaces.

The concept of (preconcave, concave) L-convergence spaces via L-ordered co-Scott closed sets is introduced and its diagonal axioms are proposed.
