Path Laplacians versus fractional Laplacians as nonlocal operators on networks

open access: yesNew Journal of Physics, 2021
Here we study and compare nonlocal diffusion processes on networks based on two different kinds of Laplacian operators. We prove that a nonlocal diffusion process on a network based on the path Laplacian operator always converges faster than the standard

Numerical Solution of Fractional Elliptic Problems with Inhomogeneous Boundary Conditions

open access: yesFractal and Fractional, 2021
The numerical solution of fractional-order elliptic problems is investigated in bounded domains. According to real-life situations, we assumed inhomogeneous boundary terms, while the underlying equations contain the full-space fractional Laplacian ...

A fractional generalization of the classical lattice dynamics approach [PDF]

open access: yes, 2016
We develop physically admissible lattice models in the harmonic approximation which define by Hamilton's variational principle fractional Laplacian matrices of the forms of power law matrix functions on the n-dimensional periodic and infinite lattice in ...

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

The Pohozaev Identity for the Fractional Laplacian [PDF]

open access: yesArchive for Rational Mechanics and Analysis, 2014
In this paper we prove the Pohozaev identity for the semilinear Dirichlet problem $(- )^s u = f(u)$ in $ $, $u \equiv 0$ in $\mathbb R^n\setminus $. Here, $s\in(0,1)$, $(- )^s$ is the fractional Laplacian in $\mathbb R^n$, and $ $ is a bounded $C^{1,1}$ domain. To establish the identity we use, among other things, that if $u$ is a bounded solution

The Spatially Variant Fractional Laplacian

open access: yesFractional Calculus and Applied Analysis, 2023
We introduce a definition of the fractional Laplacian $(-Δ)^{s(\cdot)}$ with spatially variable order $s:Ω\to [0,1]$ and study the solvability of the associated Poisson problem on a bounded domain $Ω$. The initial motivation arises from the extension results of Caffarelli and Silvestre, and Stinga and Torrea; however the analytical tools and approaches

Solutions for nonhomogeneous fractional (p, q)-Laplacian systems with critical nonlinearities

open access: yesAdvances in Nonlinear Analysis, 2022
In this article, we aimed to study a class of nonhomogeneous fractional (p, q)-Laplacian systems with critical nonlinearities as well as critical Hardy nonlinearities in RN{{\mathbb{R}}}^{N}.

Global Heat Kernel Estimates for Fractional Laplacians in Unbounded Open Sets [PDF]

open access: yes, 2009
In this paper, we derive global sharp heat kernel estimates for symmetric alpha-stable processes (or equivalently, for the fractional Laplacian with zero exterior condition) in two classes of unbounded C^{1,1} open sets in R^d: half-space-like open sets ...

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.
