Some results on infinite-dimensional convexity
This beautiful paper discusses a few intriguing topics of infinite-dimensional convexity in the spirit of V.~Klee and R.~Phelps. Among the themes appear the tilings and proximinal sets, polytopes in the sense of M.~Kadec, and approximation by convex sets with dense extreme boundary.
