Inégalité de Kato et inégalité de Kato jusqu'au bord

Abstract

Haïm Brezis and Augusto Ponce introduced and studied in their works several extensions of Kato's inequality, in particular Kato's inequalities up to the boundary involving the Laplacian and the normal derivative of the positive part of a function. Using Potential theoretic methods we answer here some questions raised in Brezis and Ponce (2008). To cite this article: A. Ancona, C. R. Acad. Sci. Paris, Ser. I 346 (2008).
