the main purpose of this paper is to consider the t-best simultaneousapproximation in fuzzy normed spaces. we develop the theory of t-bestsimultaneous approximation in quotient spaces. then, we discuss the relationshipin t-proximinality and t-chebyshevity of a given space and its quotientspace.

Abstract It is known that the class of p -vector spaces $(0 < \leq 1)$ (0<p≤1) an important generalization usual norm with rich topological and geometrical structure, but most tools general principles nat...
