What is it about?

This paper studies the complexity of the relaxed Peaceman-Rachford splitting method, an important and widely studied method, to find a zero to the sum of two maximal strongly monotone operators. The authors of the paper studied this using the hybrid proximal extragradient framework.

Why is it important?

This is among the very few studies in the literature on the method on two maximal strongly monotone operators. The results obtained improved on what is currently known in the literature.

Perspectives

The novelty of this paper is relating the relaxed Peaceman-Rachford splitting method to the hybrid proximal extragradient framework.
