Let H be a reproducing kernel Hilbert space of analytic functions on the unit disk D . The.best kernel approximation problem for H is the following: given any positive integer n.and any function f ∈ H find the best norm approximation of f by a linear combination of.no more than n kernel functions K ( z, z.k ) , 1 ≤ k ≤ n . The purpose of this paper is to prove.the existence of best kernel approximation for weighted Bergman spaces with standard.weights.
