Abstract

In this paper, a generalized form of the Bolzano theorem in classical analysis to fuzzy number space and a characterization of compact subsets in fuzzy number space are given. Some properties of the fuzzy-valued continuous functions defined on a compact set K are studied. Completeness of the space C(K,E1) of fuzzy-valued continuous functions on K endowed with the supremum metric D is proved. A characterization of compact subsets in the space (C(K,E1),D) is presented, which is a generalization of the Arzela–Ascoli theorem in classical analysis.
