A strong comparison principle for the $p$-Laplacian [PDF]

open access: hybridProceedings of the American Mathematical Society, 2007
We consider weak solutions of the differential inequality of p-Laplacian type - Δpu - f(u) ≤-Δpv - f(v) such that u p - 1.

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 ...

Some remarks on the comparison principle in Kirchhoff equations [PDF]

open access: yesRevista Matemática Iberoamericana, 2018
In this paper we study the validity of the comparison principle and the sub-supersolution method for Kirchhoff type equations. We show that these principles do not work when the Kirchhoff function is increasing, contradicting some previous results.

Comparison Principle for Weakly Coupled Cooperative Parabolic Systems with Delays

open access: goldMathematics
In this article, the validity of the comparison principle (CP) for weakly coupled quasi-linear cooperative systems with delays is proven. This is a powerful tool for studying the qualitative properties of the solutions. The CP is crucial in the proofs of

A COMPARISON OF VARIOUS ANALYTIC CHOICE PRINCIPLES [PDF]

open access: yesThe Journal of Symbolic Logic, 2021
AbstractWe investigate computability theoretic and descriptive set theoretic contents of various kinds of analytic choice principles by performing a detailed analysis of the Medvedev lattice of $\Sigma ^1_1$ -closed sets. Among others, we solve an open problem on the Weihrauch degree of the parallelization of the $\Sigma ^1_1$ -choice principle on ...

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 ...

A comparison principle for large deviations [PDF]

open access: yesProceedings of the American Mathematical Society, 1988
If { μ n } \{ {\mu _n}\} and { ν n } \left \{ {{\nu _n}} \right \} are two sequences of probability measures on a separable metric space, we give ...
