On the concentration–compactness principle for Folland–Stein spaces and for fractional horizontal Sobolev spaces

open access: diamondMathematics in Engineering, 2022
<abstract><p>In this paper we establish some variants of the celebrated concentration–compactness principle of Lions – CC principle briefly – in the classical and fractional Folland–Stein spaces. In the first part of the paper, following the main ideas of the pioneering papers of Lions, we prove the CC principle and its variant, that is the

Concentration-Compactness Principle for Moser-type Inequalities in Lorentz-Sobolev Spaces [PDF]

open access: goldPotential Analysis, 2015
Let n ∈ 𝜖, n ≥ 2, q ∈ (1, ∞) and let ${\Omega }\subset \mathbb {R}^{n}$ be an open bounded set. We study the Concentration-Compactness Principle for the embedding of the Lorentz-Sobolev space

Concentration-Compactness Principle for Trudinger–Moser’s Inequalities on Riemannian Manifolds and Heisenberg Groups: A Completely Symmetrization-Free Argument [PDF]

open access: hybridAdvanced Nonlinear Studies, 2021
The concentration-compactness principle for the Trudinger–Moser-type inequality in the Euclidean space was established crucially relying on the Pólya–Szegő inequality which allows to adapt the symmetrization argument.

Solutions of stationary Kirchhoff equations involving nonlocal operators with critical nonlinearity in RN [PDF]

open access: yesNonlinear Analysis, 2017
In this paper, we consider the existence and multiplicity of solutions for fractional Schrödinger equations with critical nonlinearity in RN. We use the fractional version of Lions' second concentration-compactness principle and concentration ...

Lower Semicontinuity of Functionals via the Concentration-Compactness Principle

open access: bronzeJournal of Mathematical Analysis and Applications, 2001
AbstractIn this paper we show the weak lower semicontinuity of some classes of functionals, using the concentration-compactness principle of P. L. Lions. These functionals involve an integral term, and we do not know whether it can be handled by the De Giorgi theorem.

EXISTENCE OF STEADY STATES FOR THE MAXWELL–SCHRÖDINGER–POISSON SYSTEM: EXPLORING THE APPLICABILITY OF THE CONCENTRATION–COMPACTNESS PRINCIPLE [PDF]

open access: greenMathematical Models and Methods in Applied Sciences, 2013
This paper reviews recent results and open problems concerning the existence of steady states to the Maxwell–Schrödinger system. A combination of tools, proofs and results are presented in the framework of the concentration–compactness method.

The Concentration-Compactness Principle in the Calculus of Variations. The limit case, Part 1

open access: bronzeRevista Matemática Iberoamericana, 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 \mathbb R^N where the invariance of \mathbb R^N

Note on the concentration-compactness principle for generalized Moser-Trudinger inequalities

open access: yesOpen Mathematics, 2012
Abstract Let Ω ⊂ ℝn, n ≥ 2, be a bounded domain and let α < n − 1. Motivated by Theorem I.6 and Remark I.18 of [Lions P.-L., The concentration-compactness principle in the calculus of variations. The limit case. I, Rev. Mat. Iberoamericana, 1985, 1(1), 145–201] and by the results of [Černý R., Cianchi A., Hencl S., Concentration ...

Concentration-compactness principle for mountain pass problems

open access: green, 2005
In the paper we show that critical sequences associated with the mountain pass level for semilinear elliptic problems on $\R^N$ converge when the non-linearity is subcritical, superlinear and satisfies the penalty condition $F_\infty(s)
