Critical point concepts: a fixed-point approach
Abstract
Inspired by the notion of critical points for DC functions and given two mappings P and Q, we introduce the concept of critical points in the fixed-point context and design and algorithm for finding such points. Connections are then made with the DC optimization case. We show that the proposed Algorithmic approach coincides with the celebrate DCA introduced by Pham Dinh Tao. The case of maximal monotone operators is also stated and investigated via a characterization of their associated resolvents.
