Lower bounds for fractional Laplacian eigenvalues [PDF]

open access: yesCommunications in Contemporary Mathematics, 2014
In this paper, we investigate eigenvalues of fractional Laplacian (–Δ)α/2|D, where α ∈ (0, 2], on a bounded domain in an n-dimensional Euclidean space and obtain a sharper lower bound for the sum of its eigenvalues, which improves some results due to Yildirim Yolcu and Yolcu in [Estimates for the sums of eigenvalues of the fractional Laplacian on a ...

Fractional Laplacian system involving doubly critical nonlinearities in $\mathbb{R}^N$

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2017
In this article, we are interested in a fractional Laplacian system in $\mathbb{R}^N$, which involves critical Sobolev-type nonlinearities and critical Hardy–Sobolev-type nonlinearities.

A mixed operator approach to peridynamics

open access: yesMathematics in Engineering, 2023
In the present paper we propose a model describing the nonlocal behavior of an elastic body using a peridynamical approach. Indeed, peridynamics is a suitable framework for problems where discontinuities appear naturally, such as fractures, dislocations,

Existence of Multiple Weak Solutions to a Discrete Fractional Boundary Value Problem

open access: yesAxioms, 2023
The existence of at least three weak solutions to a discrete fractional boundary value problem containing a p-Laplacian operator and subject to perturbations is proved using variational methods. Some applications of the main results are presented.

On the fractional Dunkl Laplacian [PDF]

open access: yesarXiv, 2021
In this paper, we present an approach to the fractional Dunkl Laplacian in a framework emerging from certain reflection symmetries in Euclidean spaces. Our main result is pointwise formulas, Bochner subordination, and an extension problem for the fractional Dunkl Laplacian as ...

Overdetermined problems with fractional laplacian [PDF]

open access: yesESAIM: Control, Optimisation and Calculus of Variations, 2015
Let $N\geq 1$ and $s\in (0,1)$. In the present work we characterize bounded open sets $ $ with $ C^2$ boundary (\textit{not necessarily connected}) for which the following overdetermined problem \begin{equation*} ( - )^s u = f(u) \text{ in $ $,} \qquad u=0 \text{ in $\mathbb{R}^N\setminus $,} \qquad(\partial_ )_s u=Const. \text{ on $\partial $}

Fractional conformal Laplacians and fractional Yamabe problems [PDF]

open access: yesAnalysis & PDE, 2013
Based on the relations between scattering operators of asymptotically hyperbolic metrics and Dirichlet-to-Neumann operators of uniformly degenerate elliptic boundary value problems, we formulate fractional Yamabe problems that include the boundary Yamabe problem studied by Escobar.

Solutions for the Problems Involving Fractional Laplacian and Indefinite Potentials

open access: yesAdvanced Nonlinear Studies, 2017
In this paper, we consider a class of Schrödinger equations involving fractional Laplacian and indefinite potentials. By modifying the definition of the Nehari–Pankov manifold, we prove the existence and asymptotic behavior of least energy solutions.
