Concentration-compactness for singular nonlocal Schrödinger equations with oscillatory nonlinearities

open access: yes, 2018
The paper is dedicated to the theory of concentration-compactness principles for inhomogeneous fractional Sobolev spaces. This subject for the local case has been studied since the publication of the celebrated works due to P.-L.

Describing lack of compactness in Sobolev spaces

open access: yes, 2010
Taken from unpublished lecture notes "Variational Methods in Quantum Mechanics" written for a course delivered at the University of Cergy-Pontoise in 2010.MasterWe review the concentration-compactness method and the profile decomposition in Sobolev ...

COMPACTNESS AND LIOUVILLE EQUATIONS

open access: yes, 2020

A concentration-compactness principle for perturbed isoperimetric problems with general assumptions

open access: yes
Derived from the concentration-compactness principle, the concept of generalized minimizer can be used to define generalized solutions of variational problems which may have components ``infinitely'' distant from each other. In this article and under mild assumptions we establish existence and density estimates of generalized minimizers of perturbed ...

The Concentration-Compactness Principle in the Calculus of Variations. (The limit case, Part I.)

open access: yes, 1985
After the study made in the locally compact case for variational problems with some translation invariance, we investigate here the variational problems (with constraints) for example in RN where the invariance of RN by the group of dilatations creates ...
