Ground state solutions for nonlinearly coupled systems of Choquard type with lower critical exponent

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
In this paper, we study the existence of ground state solutions for the following nonlinearly coupled systems of Choquard type with lower critical exponent by variational methods \begin{equation*} \begin{cases} \displaystyle-\Delta u+V(x)u=(I_\alpha\ast ...

Symmetry and Nonexistence of Positive Solutions for Weighted HLS System of Integral Equations on a Half Space

open access: yesAbstract and Applied Analysis, 2014
We consider system of integral equations related to the weighted Hardy-Littlewood-Sobolev (HLS) inequality in a half space. By the Pohozaev type identity in integral form, we present a Liouville type theorem when the system is in both supercritical and ...

On the stability of a version of nonlocal Sobolev inequality

open access: yesBulletin of Mathematical Sciences
In this paper, we investigate the stability of the corresponding nonlocal Sobolev inequality ∫ℝN|Δu|2dx≥S∗∫ℝN(|x|−α∗|u|p)updx1p,∀u∈𝒟2,2(ℝN), where [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] is the best constant.

Solutions with prescribed mass for a critical Choquard equation driven by a local-nonlocal operator [PDF]

open access: yesOpuscula Mathematica
In this paper, we study the normalized solutions of the following critical growth Choquard equation with mixed local and nonlocal operators: \[\begin{split}-\Delta u +(-\Delta)^s u &= \lambda u +\mu |u|^{p-2}u +(I_{\alpha}*|u|^{2^*_{\alpha}})|u|^{2^*_ ...

Sharp reversed Hardy--Littlewood--Sobolev inequality on the half space $\mathbb R_+^n$

open access: yes, 2016
This is the second in our series of papers concerning some reversed Hardy--Littlewood--Sobolev inequalities. In the present work, we establish the following sharp reversed Hardy--Littlewood--Sobolev inequality on the half space $\mathbb R_+^n$ \[ \int_ ...

Function spaces for decoupling

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 4, April 2026.
Abstract We introduce new function spaces LW,sq,p(Rn)$\mathcal {L}_{W,s}^{q,p}(\mathbb {R}^{n})$ that yield a natural reformulation of the ℓqLp$\ell ^{q}L^{p}$ decoupling inequalities for the sphere and the light cone. These spaces are invariant under the Euclidean half‐wave propagators, but not under all Fourier integral operators unless p=q$p=q$, in ...

Hardy–Littlewood–Sobolev inequalities on compact Riemannian manifolds and applications

open access: yesJournal of Differential Equations, 2016
In this paper we extend Hardy-Littlewood-Sobolev inequalities on compact Riemannian manifolds for dimension $n\ne 2$. As one application, we solve a generalized Yamabe problem on locally conforamlly flat manifolds via a new designed energy functional and a new variational approach.

Generalized quasi‐geostrophic equation in critical Lorentz–Besov spaces, based on maximal regularity

open access: yesMathematische Nachrichten, Volume 299, Issue 3, Page 637-660, March 2026.
Abstract We consider the quasi‐geostrophic equation with its principal part (−Δ)α${(-\mathrm{\Delta})^{\alpha}}$ for α>1/2$\alpha >1/2$ in Rn$\mathbb {R}^n$ with n≥2$n \ge 2$. We show that for every initial data θ0∈Ḃr,q1−2α+nr$\theta _0 \in \dot{B}^{1-2\alpha + \frac{n}{r}}_{r, q}$ with 1

Existence of groundstates for Choquard type equations with Hardy–Littlewood–Sobolev critical exponent

open access: yesBoundary Value Problems, 2021
In this paper, we consider a class of Choquard equations with Hardy–Littlewood–Sobolev lower or upper critical exponent in the whole space R N $\mathbb{R}^{N}$ . We combine an argument of L. Jeanjean and H. Tanaka (see (Proc. Am. Math. Soc. 131:2399–2408,
