Strong Comparison Principle for $p-$harmonic functions in Carnot-Caratheodory spaces [PDF]

open access: greenarXiv, 2017
We extend Bony's propagation of support argument \cite{Bony} to $C^1$ solutions of the non-homogeneous sub-elliptic $p-$Laplacian associated to a system of smooth vector fields satisfying H\"ormander's finite rank condition. As a consequence we prove a strong maximum principle and strong comparison principle that generalize results of Tolksdorf \cite ...

A Liouville comparison principle for solutions of quasilinear singular parabolic inequalities [PDF]

open access: hybridAdvances in Nonlinear Analysis, 2015
We obtain a Liouville comparison principle for entire weak solutions (u,v) of quasilinear singular parabolic second-order partial differential inequalities of the form ut-A(u)-|u|q-1u≥vt-A(v)-|v|q-1v${ u_t - A(u)-|u|^{q-1}u \ge v_t - A (v)-|v|^{q-1}v ...

A new fixed-time stability criterion for fractional-order systems

open access: yesAIMS Mathematics, 2022
In this work, we study the fixed-time stability of fractional-order systems. By virtue of the properties of Riemann-Liouville fractional derivative and the comparison principle, we derive a new fixed-time stability theorem for fractional-order systems ...

Comparison principles and applications to mathematical modelling of vegetal meta-communities

open access: yesMathematics in Engineering, 2022
This article partakes of the PEGASE project the goal of which is a better understanding of the mechanisms explaining the behaviour of species living in a network of forest patches linked by ecological corridors (hedges for instance).

Propagation dynamics in an SIRS model with general incidence functions

open access: yesMathematical Biosciences and Engineering, 2023
This paper studies the initial value problems and traveling wave solutions in an SIRS model with general incidence functions. Linearizing the infected equation at the disease free steady state, we can define a threshold if the corresponding basic ...

Improvements on overdetermined problems associated to the p-Laplacian

open access: yesMathematics in Engineering, 2022
This work presents some improvements on related papers that investigate certain overdetermined problems associated to elliptic quasilinear operators. Our model operator is the p-Laplacian.

Exponential Synchronization of Partially Coupled Heterogeneous Networks With Time-Delays and Heterogeneous Impulsess

open access: yesIEEE Access, 2021
This work focuses on exponential synchronization for a class of partially coupled heterogeneous networks with time-delays and heterogeneous impulses. The synchronization targets are selected as the common equilibrium solution and the average trajectory ...

Blow-up and global existence for the inhomogeneous porous medium equation with reaction [PDF]

open access: yesRendiconti di Matematica e delle Sue Applicazioni, 2021
We study finite time blow-up and global existence of solutions to the Cauchy problem for the porous medium equation with a variable density ρ(x) and a power-like reaction term. We firstly consider the case that ρ(x) decays at infinity like the critical

Motion by crystalline-like mean curvature: A survey

open access: yesBulletin of Mathematical Sciences, 2022
We consider a class of anisotropic curvature flows called crystalline curvature flows. We present a survey on this class of flows with special emphasis on the well-posedness of its initial value problem.

Backward Stochastic Differential Equations Driven by a Jump Markov Process with Continuous and Non-Necessary Continuous Generators

open access: yesFractal and Fractional, 2022
We deal with backward stochastic differential equations driven by a pure jump Markov process and an independent Brownian motion (BSDEJs for short). We start by proving the existence and uniqueness of the solutions for this type of equation and present a ...
