On a Lemma by Brézis and Haraux
arXiv:2501.11662
Abstract
We propose several applications of an often overlooked part of the 1976 paper by Brézis and Haraux, in which the Brézis--Haraux theorem was established. Our results unify and extend various existing ones on the range of a linearly composite monotone operator and provide new insight into their seminal paper.
