Maximum principles for nonlocal parabolic Waldenfels operators [PDF]

open access: diamondBulletin of Mathematical Sciences, 2019
As a class of Lévy type Markov generators, nonlocal Waldenfels operators appear naturally in the context of investigating stochastic dynamics under Lévy fluctuations and constructing Markov processes with boundary conditions (in particular the ...

Maximum principles and related problems for a class of nonlocal extremal operators [PDF]

open access: hybridAnnali di Matematica Pura ed Applicata, 2022
We study the validity of the comparison and maximum principles and their relation with principal eigenvalues, for a class of degenerate nonlinear operators that are extremal among operators with one-dimensional fractional diffusion.

Mixed local and nonlocal elliptic operators: regularity and maximum principles [PDF]

open access: greenCommunications in Partial Differential Equations, 2021
We develop a systematic study of the superpositions of elliptic operators with different orders, mixing classical and fractional scenarios. For concreteness, we focus on the sum of the Laplacian and the fractional Laplacian, and we provide structural ...

Maximum principles for time-fractional Caputo-Katugampola diffusion equations

open access: diamond, 2017
Maximum and minimum principles for time-fractional Caputo-Katugampola diffusion operators are proposed in this paper. Several inequalities are proved at extreme points.

Maximum principles, Liouville-type theorems and symmetry results for a general class of quasilinear anisotropic equations

open access: yesAdvances in Nonlinear Analysis, 2016
This paper is concerned with a general class of quasilinear anisotropic equations. We first derive some maximum principles for two appropriate P-functions, in the sense of Payne (see the book of Sperb [18]).

Maximum Principles for Discrete and Semidiscrete Reaction-Diffusion Equation

open access: yesDiscrete Dynamics in Nature and Society, 2015
We study reaction-diffusion equations with a general reaction function f on one-dimensional lattices with continuous or discrete time ux′  (or  Δtux)=k(ux-1-2ux+ux+1)+f(ux), x∈Z.
