On the Fractional Dunkl Laplacian

open access: yes, 2022
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 well.

Laplacian Fractional Revival on Graphs [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2021
We develop the theory of fractional revival in the quantum walk on a graph using its Laplacian matrix as the Hamiltonian. We first give a spectral characterization of Laplacian fractional revival, which leads to a polynomial time algorithm to check this phenomenon and find the earliest time when it occurs.

A detour on a class of nonlocal degenerate operators

open access: yesBruno Pini Mathematical Analysis Seminar, 2023
We present some recent results on a class of degenerate operators which are modeled on the fractional Laplacian, converge to the truncated Laplacian, and are extremal among operators with fractional diffusion along subspaces of possibly different ...

Fast implicit difference schemes for time‐space fractional diffusion equations with the integral fractional Laplacian [PDF]

open access: yesMathematical methods in the applied sciences, 2020
In this paper, we develop two fast implicit difference schemes for solving a class of variable‐coefficient time–space fractional diffusion equations with integral fractional Laplacian (IFL).

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

On the existence of ground state solutions to critical growth problems nonresonant at zero

open access: yesComptes Rendus. Mathématique, 2021
We prove the existence of ground state solutions to critical growth $p$-Laplacian and fractional $p$-Laplacian problems that are nonresonant at zero.

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 ...

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 ...
