The Farthest and the Nearest Points of Sets
Journal of convex analysis, Tome 25 (2018) no. 3, pp. 1019-1031
In a reflexive strictly convex real Banach space we established relationship between the metric projection on some closed convex subset and the metric antiprojection on another ("dual") closed convex subset. Some applications of the result are considered.
