Sobolev Inequalities with Remainder Terms

open access: yesJournal of Functional Analysis, 1985
Le résultat principal concerne l'inégalité de Sobolev \[ \int_{\Omega}| \nabla u|^ 2\geq S_ n\| u\|^ 2_{2^*}+C(\Omega)[u]^ 2_{2^*/2}. \] Pour toute fonction \(u\in H^ 1_ 0(\Omega)\), où \(\Omega \subset {\mathbb{R}}^ n\) est un ouvert borné, \(S_ n\) est la meilleure constante de Sobolev dans \({\mathbb{R}}^ n\), \(2^*={\mathfrak n}/(n-2)\) et [ \(]_ p\

Some inequalities for Sobolev integrals

open access: yesElectronic Journal of Differential Equations, 2009
We present some inequalities for Sobolev integrals for functions of one variable which are generalization of Dirichlet principle for harmonic functions.

Hardy–Sobolev interpolation inequalities

open access: yesCalculus of Variations and Partial Differential Equations
AbstractWe derive a family of interpolation estimates which improve Hardy’s inequality and cover the Sobolev critical exponent. We also determine all optimizers among radial functions in the endpoint case and discuss open questions on nonrestricted optimizers.

Hardy and Sobolev inequalities on antisymmetric functions

open access: yesBulletin of Mathematical Sciences
We obtain sharp Hardy inequalities on antisymmetric functions, where antisymmetry is understood for multi-dimensional particles. Partially it is an extension of the paper [Th. Hoffmann-Ostenhof and A.

On weighted Calderón-Zygmund singular integrals and applications

open access: yesJournal of Innovative Applied Mathematics and Computational Sciences, 2022
This paper studies some weighted norm inequalities related to some Calderon-Zygmund singular integrals. Applications to the Sobolev-Gagliardo-Nirenberg inequality, differential forms, and the potential equation du = f are given.

Nonlinear Elliptic Equations with Maximal Growth Range

open access: yesPesquimat, 2017
In this work we are interested in studying the existence of nontrivial weak solutions for a class of nonlinear elliptic equations defined in a bounded domain in dimension two, where the nonlinearities possess maximal exponential growth range motivated by

Poincaré and Log–Sobolev Inequalities for Mixtures [PDF]

open access: yesEntropy, 2019
This work studies mixtures of probability measures on R n and gives bounds on the Poincaré and the log–Sobolev constants of two-component mixtures provided that each component satisfies the functional inequality, and both components are close in the χ 2 -distance.

Hardy-Littlewood-Sobolev Inequalities on p-Adic Central Morrey Spaces

open access: yesJournal of Function Spaces, 2015
We establish the Hardy-Littlewood-Sobolev inequalities on p-adic central Morrey spaces. Furthermore, we obtain the λ-central BMO estimates for commutators of p-adic Riesz potential on p-adic central Morrey spaces.

Stability for the Sobolev inequality in cones

open access: yesJournal of Differential Equations
We prove a quantitative Sobolev inequality in cones of Bianchi-Egnell type, which implies a stability property. Our result holds for any cone as long as the minimizers of the Sobolev quotient are nondegenerate, which is the case of most cones. When the minimizers are the classical bubbles we have more precise results.
