Maximum Principles for Discrete and Semidiscrete Reaction-Diffusion Equation [PDF]

open access: goldDiscrete 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.

Some maximum principles for solutions of a class of partial differential equations in Ω⊂ℝn [PDF]

open access: goldInternational Journal of Mathematics and Mathematical Sciences, 2000
We find maximum principles for solutions of semilinear elliptic partial differential equations of the forms: (1) Δ2u+αf(u)=0, α∈ℝ+ and (2) ΔΔu+α(Δu)k+gu=0, α≤0 in some region Ω⊂ℝn.

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

open access: greenCommunications in Partial Differential Equations, 2020
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 nonlocal parabolic Waldenfels operators [PDF]

open access: yesBulletin 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 for a family of nonlocal boundary value problems [PDF]

open access: greenAdvances in Difference Equations, 2004
We study a family of three-point nonlocal boundary value problems (BVPs) for an nth-order linear forward difference equation. In particular, we obtain a maximum principle and determine sign properties of a corresponding Green function.

Peyronie's Reconstruction for Maximum Length and Girth Gain: Geometrical Principles [PDF]

open access: goldAdvances in Urology, 2008
Peyronie's disease has been associated with penile shortening and some degree of erectile dysfunction. Surgical reconstruction should be based on giving a functional penis, that is, rectifying the penis with rigidity enough to make the sexual intercourse.

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]).
