Firm nonexpansiveness

WebNonexpansiveness of proximal operators. In this problem we show that for a convex function f (not necessarily differentiable), its proximal operator is nonexpansive, i.e., Proxf (01) – Proxf (02) 5 01 - 02 , where Proxy (01) = arg min f (0) + 3 0 – 0,112, with the following steps: (a) Show that 01 - Prox (01) e af (01).
