This paper provides some conditions to obtain best uniform coapproximation. Some error
estimates are determined. A relation between interpolation and best uniform …

This paper delineates some fundamental properties of the set of strongly unique best
coapproximation. Uniqueness of strongly unique best coapproximation is studied. Some …

As a counterpart to best approximation in normed linear spaces, best coapproximation was
introduced by Franchetti and Furi,[3], in 1972. If X is a Banach space, E (X) the Köthe …

The tools and techniques employed in abstract approximation theory are listed. Several
important applications stem out of the theory and will prove to be useful in mathematical …

In this paper we study the concept of t-best coapproximation in fuzzy normed spaces. We
introduce the notions of t-best coapproximation, t-coproximinal sets, t-coChebyshev sets and …

In this paper we study the concept of-t best coapproximation in fuzzy 2-normed spaces. We
introduce the notions of-t best coapproximation,-t coproximinal sets,-t coChebyshev sets and …

As a counterpart to best approximation in normed linear spaces, best coapproximation was
introduced by Franchetti and Furi. In this paper, we apply the above coapproximation, and …

The main purpose of this paper is to consider the t-best co-approximation and t-best
simultaneous co-approximation in fuzzy normed spaces. We develop the theory of t-best co …

Let X be a Banach space,(I, μ) be a finite measure space and G be a closed subspace of X.
In this paper, we study the problem of best coapproximation in the metric space L p (I, X), 0< …

In this paper, we study the concept of t-best coapproximation in fuzzy anti-2-normed linear
spaces. We introduce the notion of t-best coapproximation, t-coproximinal sets, t …
