• Abstract

This paper is part II of "{On Copositive Approximation in Spaces of Continuous Functions}". In this paper the author shows that if Q is any compact subset of real numbers, and M is any finite dimensional strict Chebyshev subspace of C(Q) then for any admissible function $f\in C(Q)\backslash M,$ the best copositive approximation to $f$ from M is unique.
