Some results on 2-best coapproximation in quotient generalized 2-normed spaces
Summary: In this paper we study the concept of 2-best coapproximation in generalized 2-normed spaces. We introduce the notions of 2-best coapproximation, 2-coproximinal sets and 2-cochebyshev sets and prove some interesting theorems to characterization of 2-best coapproximation elements in quotient spaces.
