“…With respect to convexity, convergence in this sense is stable with respect to duality, as established implicitly by Walkup and Wets [WW] and then by Wijsman [Wi]: If (An) is a sequence of closed convex sets in R" Kuratowski convergent to A , we have the convergence of the polar sequence (A°n) to A°. Attempts to obtain a suitable infinite dimensional generalization of this convergence notion have focused on the notion of Mosco convergence [Mol,Mo2,BB,BF,At,SW,So,Ts] and the associated Mosco topology [Be3,Be4]. Unfortunately, these ideas do not work well without reflexivity [BB].…”
