Generalized Morrey-Campanato estimates for elliptic equations with coefficients of integrable oscillation
Laurent Seppecher
This work concerns regularity properties of weak solutions to elliptic equations in divergence form -div(au) = div F , under low regularity assumptions on both the coeffici…

Multi-parameter identification in systems of PDEs from internal data
Ãlie Bretin, Eliott Kacedan, Laurent Seppecher
This article aims to present a general analysis of a class of inverse problems that consists in recovering the elliptic parameter maps in systems of PDEs, such as the linear elasti…
