Let M be a convex Chebyshev subset of a uniformly convex and uniformly smoothBanach space.It is proved that the metric projection P_M of X onto M is uniformly c
The object of this paper is to establish the pointwise estimations of approximation of functions in C~1 andtheir derivatives by Hermite interpolation polynomial
Some results from the theory of best (or best simultaneous) approximation in a narmed linear space have been extended to a normed almost linear space [strong no
