Remarks on the Generalized Fractional Laplacian Operator

open access: yesMathematics, 2019
The fractional Laplacian, also known as the Riesz fractional derivative operator, describes an unusual diffusion process due to random displacements executed by jumpers that are able to walk to neighbouring or nearby sites, as well as perform excursions ...

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,

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.

Existence and Uniqueness of Solutions to Four-Point Impulsive Fractional Differential Equations with p-Laplacian Operator

open access: yesMathematics, 2022
In this paper, by using fixed-point theorems, the existence and uniqueness of positive solutions to a class of four-point impulsive fractional differential equations with p-Laplacian operators are studied. In addition, three examples are given to justify

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 ...

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 $}

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.

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.
