Abstract

By using the fixed point technique, we prove the stability of sixtic functional equations. Our results are studied and proved in the framework of fuzzy modular spaces (brie y, FM-spaces). The lower semi continuous (brie y, l.s.c.) and \(\beta\)-homogeneous are necessary conditions for this work.
