Stability of complement value problems for -Lévy operators

Guy Foghem

We set up a general framework tailor-made to solve complement value problems governed by symmetric nonlinear integrodifferential -Lévy operators. A prototypical example of integ…

A general framework for nonlocal Neumann problems

Guy Foghem, Moritz Kassmann

Within the framework of Hilbert spaces, we solve nonlocal problems in bounded domains with prescribed conditions on the complement of the domain. Our main focus is on the inhomogen…

Nonlocal Gagliardo-Nirenberg-Sobolev type inequality

Guy Foghem

We establish Gagliardo-Nirenberg-Sobolev type inequalities on nonlocal Sobolev spaces driven by -Lévy integrable kernels, by imposing some appropriate growth conditions on the a…

Nonlocal complement value problem for a global in time parabolic equation

Jean-Daniel Djida, Guy F. Foghem Gounoue, Yannick Kouakep Tchaptchie

The overreaching goal of this paper is to investigate the existence and uniqueness of weak solution of a semilinear parabolic equation with double nonlocality in space and in time…

A Remake of Bourgain-Brezis-Mironescu Characterization of Sobolev Spaces

Guy Fabrice Foghem Gounoue

We introduce a large class of concentrated -Lévy integrable functions approximating the unity, which serves as the core tool from which we provide a nonlocal characterization of…

Mosco convergence of nonlocal to local quadratic forms

Guy Fabrice Foghem Gounoue, Moritz Kassmann, Paul Voigt

We study sequences of nonlocal quadratic forms and function spaces that are related to Markov jump processes in bounded domains with a Lipschitz boundary. Our aim is to show the co…
