The problem of approximating a finite number of functions simultaneously is considered. For a general class of norms, a characterization of best approximations is given. The result generalizes recent work concerned specifically with the Chebyshev norm. 1993 Academic Press, Inc.

Let C be a closed bounded convex subset of a Banach space E which has the origin of E as an interior point and let p C denote the Minkowski functional with respect to C. Given a closed set X/E and a point u # E we consider a minimization problem min C (u, X ) which consists in proving the existence
