Abstract

The aim of this paper is to study the convergence of two proximal algorithms via the
notion of (a, r)-relaxed cocoercivity without Lipschitzian continuity. We will show that this notion
is enough to obtain some interesting convergence theorems without any Lipschitz-continuity
assumption. The relaxed cocoercivity case is also investigated.
