Abstract
For uniformly convex asymmetric spaces, questions concerning nonempty intersections of a nested system of bounded convex closed sets are considered. Questions concerning the density of sets of points of existence and approximative uniqueness are studied in these spaces for the case of nonempty closed subsets.
