Retractions of Fuzzy Flat Robertson-Walker Space

A. E. El-Ahmady, A. S. Al-Luhaybi

Abstract



Our aim in the present paper is to introduce and study a new type of metric, namely fuzzy flat Robertson-Walker space metric. New types of fuzzy retractions of fuzzy flat Robertson-Walker space are deduced. Types of fuzzy deformation retracts of fuzzy flat Robertson-Walker space are presented. The relations between the fuzzy foldings and the fuzzy deformation retracts of fuzzy flat Robertson-Walker space are deduced. Types of fuzzy foldings and fuzzy deformation retract of fuzzy tangent space of fuzzy submanifolds in fuzzy flat Robertson –Walker space is presented.

Keywords
