BEST CO-APPROXIMATIONANDBESTSIMULTANEOUS CO-APPROXIMATION ININTUITIONISTIC FUZZY NORMED LINEARSPACES

Abstract

The main purpose of this paper is to study the t-best co-approximation and t-best simultaneous co-approximation in  intuitionistic fuzzy normed spaces. We develop the theory of t-best co-approximation and t-best simultaneous co-approximation in quotient spaces. This new concept is employed  by us to improve various characterisations of t-co-proximinal and t-co-Chebyshev sets                                                                                                                                      .
