• t -BEST COAPPROXIMATION IN FUZZY ANTI-NORMED SPACES

Majid Abrishami-Moghaddam*

Abstract


In present paper the concept of t-best coapproximation in fuzzy anti-normed spaces is studid and introduced the notions of t-best coapproximation, t-coproximinal sets, t-coChebyshev sets and t-orthogonality. Lastly, we have proved some interesting theorems to characterization of t-best coapproximation elements.


Keywords


Fuzzy anti-normed spaces, t-best coapproximation, t-coproximinal sets, t-coChebyshev sets, t-quasi-coChebyshev sets, t-orthogonality.
