Existence of regular and singular bound state solutions to a quasilinear equation

open access: yesBoundary Value Problems
The existence of regular and singular bound state solutions to △ p u + f ( u ) = 0 , r ∈ R n ∖ { 0 } $$ \triangle _{p}u+f(u)=0,~~~r\in \mathbb{R}^{n}\backslash \{0\} $$ is considered. Our result concerns the solution according to its behavior as r → 0 $r\

Existence of a ground-state solution for a quasilinear Schrödinger system

open access: yesFrontiers in Physics
In this paper, we consider the following quasilinear Schrödinger system.−Δu+u+k2Δ|u|2u=2αα+β|u|α−2u|v|β,x∈RN,−Δv+v+k2Δ|v|2v=2βα+β|u|α|v|β−2v,x∈RN,where k < 0 is a real constant, α > 1, β > 1, and α + β < 2*.

BEST CONSTANTS AND POHOZAEV IDENTITY FOR HARDY–SOBOLEV-TYPE OPERATORS

open access: yesCommunications in Contemporary Mathematics, 2013
This paper is threefold. Firstly, we reformulate the definition of the norm induced by the Hardy inequality (see [J. L. Vázquez and N. B. Zographopoulos, Functional aspects of the Hardy inequality. Appearance of a hidden energy, preprint (2011); http://arxiv.

Nonlocal elliptic equations with mixed fractional Laplacians: stability and nonexistence results

open access: yesFrontiers in Applied Mathematics and Statistics
In this study, we investigate the non-existence of solutions to the non-linear elliptic equation involving mixed fractional Laplacians: (-Δ)s1u+(-Δ)s2u=|u|p-1u in ℝn,where n ≥ 2s1, 0 < s2 < s1 < 1, and p > 1.

Boundary charges and integral identities for solitons in (d+1)-dimensional field theories

open access: yesNuclear Physics B, 2017
We establish a 3-parameter family of integral identities to be used on a class of theories possessing solitons with spherical symmetry in d spatial dimensions.

Fractional Hadamard formulas, Pohozaev type identities and applications

open access: yes, 2022
The thesis is composed of four Chapters. In the first Chapter, the boundary expression of the one-sided shape derivative of nonlocal Sobolev best constants is derived. As a simple consequence, we obtain the fractional version of the so-called Hadamard formula for the torsional rigidity and the first Dirichlet eigenvalue.

Ground-state solutions for fractional Kirchhoff-Choquard equations with critical growth

open access: yesAdvances in Nonlinear Analysis
We study the following fractional Kirchhoff-Choquard equation: a+b∫RN(−Δ)s2u2dx(−Δ)su+V(x)u=(Iμ*F(u))f(u),x∈RN,u∈Hs(RN),\left\{\begin{array}{l}\left(a+b\mathop{\displaystyle \int }\limits_{{{\mathbb{R}}}^{N}}{\left|{\left(-\Delta )}^{\frac{s}{2}}u\right|}
