| Abstract: | Summary The purpose of this paper is to unify a number of continuity, perturbation, and discretization properties of best approximations in normed linear spaces or in metric or semimetric spaces. It extends work of Aubin and, more specifically, of Daniel.Research supported in part by AEC AT(45-1)-1947 |
