Existence results of infinitely many weak solutions of a singular subelliptic system on the Heisenberg group

open access: yesActa Universitatis Sapientiae: Mathematica, 2022
This article shows the existence and multiplicity of weak solutions for the singular subelliptic system on the Heisenberg group {-Δℍnu+a(ξ)u(|z|4+t2)12=λFu(ξ,u,v)in   Ω,-Δℍnv+b(ξ)v(|z|4+t2)12=λFv(ξ,u,v)in   Ω,u=v=0on  ∂Ω.\left\{ {\matrix{ { - {\Delta _{

On the H.-Q. Li inequality on step-two Carnot groups [PDF]

open access: yes, 2023
In this note we show that the gradient estimate of the heat semigroup, or more precisely the H.-Q. Li inequality, is preserved under tensorization, some suitable group epimorphism, and central sum. We also establish the Riemannian counterpart of the H.-Q.

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)=\

Bitsadze-Samarskii type problem for the integro-differential diffusion-wave equation on the Heisenberg group [PDF]

open access: yes, 2020
This paper deals with the fractional generalization of the integro-differential diffusion-wave equation for the Heisenberg sub-Laplacian, with homogeneous Bitsadze-Samarskii type time-nonlocal conditions. For the considered problem, we show the existence,

On the existence of nonnegative radial solutions for Dirichlet exterior problems on the Heisenberg group

open access: yesDemonstratio Mathematica, 2023
We investigate the existence and nonexistence of nonnegative radial solutions to exterior problems of the form ΔHmu(q)+λψ(q)K(r(q))f(r2−Q(q),u(q))=0{\Delta }_{{{\mathbb{H}}}^{m}}u\left(q)+\lambda \psi \left(q)K\left(r\left(q))f\left({r}^{2-Q}\left(q),u ...

(p,Q) systems with critical singular exponential nonlinearities in the Heisenberg group

open access: yesOpen Mathematics, 2020
The paper deals with the existence of solutions for (p,Q)(p,Q) coupled elliptic systems in the Heisenberg group, with critical exponential growth at infinity and singular behavior at the origin.

On Kac's principle of not feeling the boundary for the Kohn Laplacian on the Heisenberg group [PDF]

open access: yes, 2015
In this note we construct an integral boundary condition for the Kohn Laplacian in a given domain on the Heisenberg group extending to the setting of the Heisenberg group M. Kac's "principle of not feeling the boundary".

The Neumann problem on the domain in 𝕊3 bounded by the Clifford torus

open access: yesAdvanced Nonlinear Studies, 2023
In this study, the solution of the Neumann problem associated with the CR Yamabe operator on a subset Ω\Omega of the CR manifold S3{{\mathbb{S}}}^{3} bounded by the Clifford torus Σ\Sigma is discussed.
