L-fuzzy closure operator

Abstract

The aim of this paper is to study L-fuzzy closure operator in L-fuzzy topological spaces. We introduce two kinds of L-fuzzy closure operators from different point view and prove that both L - TFCS - the category of topological L-fuzzy closure spaces - and L-PTFCS - the category of topological pointwise L-Juzzy closure spaces - are isomorphic to L-FCTOP. © 2007 Universidad Católica del Norte, Departamento de Matemáticas.
