      Abstract

      We prove that (a) in a reflexive space, for any linearly bounded but unbounded closed convex subset the non-support functionals are a dense $G_\delta$ subset of the polar set, and (b) any non-semicoercive proper convex lsc [weak$^*$-lsc] function in a [dual] Banach space has a generic [dense $G_\delta$] set of $L^\infty$-perturbations which do not attain their infimum. We also characterize the proper convex functions that have inf-nonattaining $L^\infty$-perturbations.This results also in a criterion for reflexivity.
