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

A Remark on the Concentration Compactness Principle in Critical Dimension [PDF]
Communications on Pure and Applied Mathematics, 2021 AbstractWe prove some refinements of the concentration compactness principle for Sobolev space W1, n on a smooth compact Riemannian manifold of dimension n. As an application, we extend Aubin's theorem for functions on with zero first‐order moments of the area element to the higher‐order moments case.

Existence and concentration of solutions for a p-laplace equation with potentials in R^N
Electronic Journal of Differential Equations, 2010 We study the p-Laplace equation with Potentials $$ -hbox{div}(| abla u|^{p-2} abla u)+lambda V(x)|u|^{p-2}u=|u|^{q-2}u, $$ $uin W^{1,p}(mathbb{R}^N)$, $xin mathbb{R}^N$ where $2leq p$, $p<q<p^{*}$. Using a concentration-compactness principle

Electronic Journal of Qualitative Theory of Differential Equations, 2023 In this paper, we obtain the multiplicity of homoclinic solutions for a class of asymptotically autonomous Hamiltonian systems with indefinite sign potentials. The concentration-compactness principle is applied to show the compactness. As a byproduct, we

Existence and Symmetry of Solutions for a Class of Fractional Schrödinger–Poisson Systems
Mathematics, 2021 In this paper, we investigate a class of Schrödinger–Poisson systems with critical growth. By the principle of concentration compactness and variational methods, we prove that the system has radially symmetric solutions, which improve the related results

The concentration-compactness principles for W s,p(·,·)(ℝ N ) and application
Advances in Nonlinear Analysis, 2020 Résumé Nous obtenons un enrobage critique puis des principes de concentration-compacité pour des espaces de Sobolev fractionnaires à exposants variables. Comme une application de ces résultats, nous obtenons l'existence de nombreuses solutions pour une classe de problèmes non locaux critiques avec des exposants variables, ce qui est même nouveau pour ...

The concentration-compactness principle for variable exponent spaces and applications
Electronic Journal of Differential Equations, 2009 In this article, we extend the well-known concentration - compactness principle by Lions to the variable exponent case. We also give some applications to the existence problem for the p(x)-Laplacian with critical growth.
