| Abstract: | |||
| In this paper we establish criteria for the stability of the proximal mapping Prox f φ= (∂φ + ∂f )-1 associated to the proper lower semicontinuous convex functions φ and f on a reflexive Banach space X. We prove that, under certain conditions, if the convex functions φn converge in the sense of Mosco to φ and if ξn converges strongly to ξ then Prox fφn( ξn ) converges weakly and, if f is also totally convex, then it converges strongly to Proxf φ(ξ). | |||
