Sharp Hardy–Littlewood–Sobolev inequalities on the octonionic Heisenberg group [PDF]

open access: yesCalculus of Variations and Partial Differential Equations, 2016
The Hardy-Littlewood-Sobolev inequality for the conjugate exponent on a group of Heisenberg type has the form \[ \left|\iint_{G\times G}\frac{\overline{f(u)}g(v)}{|u^{-1}v|^\lambda}dudv\right|\lesssim\|f\|_p\|g\|_p, \] where ...

Resistance Conditions and Applications

open access: yesAnalysis and Geometry in Metric Spaces, 2013
This paper studies analytic aspects of so-called resistance conditions on metric measure spaces with a doubling measure. These conditions are weaker than the usually assumed Poincaré inequality, but however, they are sufficiently strong to imply several ...

Stability of Hardy Littlewood Sobolev inequality under bubbling

open access: yesCalculus of Variations and Partial Differential Equations, 2023
AbstractIn this note we will generalize the results deduced in Figalli and Glaudo (Arch Ration Mech Anal 237(1):201–258, 2020) and Deng et al. (Sharp quantitative estimates of Struwe’s Decomposition. Preprint http://arxiv.org/abs/2103.15360, 2021) to fractional Sobolev spaces. In particular we will show that for $$s\in (0,1)$$

Hardy inequality: genesis and applications [PDF]

open access: yes, 2022
openArgomento principale della tesi è la disuguaglianza di Hardy. Dopo averla introdotta nella sua forma sia discreta che continua, dimostrata e averne dato qualche generalizzazione, introdurremo la nozione di spazio di Sobolev, illustrando le ...

Existence of positive solutions to negative power nonlinear integral equations with weights

open access: yesBoundary Value Problems, 2020
This paper is devoted to the existence and non-existence of positive solutions to the following negative power nonlinear integral equation related to the sharp reversed Hardy–Littlewood–Sobolev inequality: f q − 1 ( x ) = ∫ Ω K ( x ) f ( y ) K ( y ) | x −

On the critical Choquard-Kirchhoff problem on the Heisenberg group

open access: yesAdvances in Nonlinear Analysis, 2022
In this paper, we deal with the following critical Choquard-Kirchhoff problem on the Heisenberg group of the form: M(‖u‖2)(−ΔHu+V(ξ)u)=∫HN∣u(η)∣Qλ∗∣η−1ξ∣λdη∣u∣Qλ∗−2u+μf(ξ,u),M\left(\Vert u{\Vert }^{2})\left(-{\Delta }_{{\mathbb{H}}}u\left+V\left(\xi )u)=\

Biharmonic system with Hartree-type critical nonlinearity

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2023
In this article, we investigate the multiplicity results of the following biharmonic Choquard system involving critical nonlinearities with sign-changing weight function: \begin{align*} \begin{cases} \Delta^{2}u = \lambda F(x) |u|^{r-2}u+ H(x)\left ...
