This paper gives a counterexample that the strong unicity fails for best monotone approximation by reciprocals of polynomials and establishes the strong unicity of order \(1 / 2\) for some class of functions. 1994 Academic Press, Inc.
The purpose of this paper is to extend several results in the theory of generalized rational approximation. Let X be a compact space and for f ~ C(X) define Ilfll ~ max{Jf(x)l : x E X}. Suppose that P and Q are two finite-dimensional subspaces of C(X). Then, in generalized rational approximation, o
