The purpose of this paper is to introduce new types of contraction condition for a pair of maps $(S,T)$ in metric spaces. We give convergence and existence results of best proximity points of such maps in the setting of uniformly convex Banach spaces

We generalize and extend Brosowski-Meinardus type results on invariant points from the set of best approximation to the set of 𝜀-simultaneous approximation. As a consequence some results on 𝜀-approximation and best approximation are also deduce

A round metric space is the one in which closure of each open ball is the corresponding closed ball. By a sleek metric space, we mean a metric space in which interior of each closed ball is the corresponding open ball. In this, article we establish s

In this article we discuss metric spaces in which closure of open balls are the corresponding closed balls, and interior of closed balls are the corresponding open balls. Moreover, we try to explore relationships between these two assertions.

We introduce partial generalized convex contractions of order $4$ and rank $4$ using some auxiliary functions. We present some results on approximate fixed points and fixed points for such class of mappings having no continuity condition in $\alpha $

For a bounded subset K of a metric space (X, d), an element k0 ϵ K is called a farthest point to an x ϵ X if . The set of all farthest points to x in K is denoted by FK(x). The set K is sai...

A linear metric space (X, d) is called a convex linear metric space if for all x, y in X, it also satisfies $$d(\lambda x+(1-\lambda )y,0)\le \lambda d(x,0)+(1-\lambda )d(y,0)$$ whenever $$0\le \lambda \le 1$$ . Such spaces, known to be more general

A Chebyshev center of a set A in a metric space (X,d) is a point of X best approximating the set A i.e., it is a point x0 ? X such that supy?A d(x0,y) = infx?X supy?A d(x,y). We discuss the existence and uniqueness of such points in metric spaces the
