Equivalents of maximum principles for several spaces

open access: yesTopological Algebra and its Applications, 2022
According to our long-standing Metatheorem, certain maximum theorems can be equivalently reformulated to various types of fixed point theorems, and conversely.

About nondecreasing solutions for first order neutral functional differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
Conditions that solutions of the first order neutral functional differential equation \[ (Mx)(t)\equiv x^{\prime }(t)-(Sx^{\prime })(t)-(Ax)(t)+(Bx)(t)=f(t), t\in \lbrack 0,\omega ], \] are nondecreasing are obtained.

Properties of switching jump diffusions: Maximum principles and Harnack inequalities [PDF]

open access: yesBernoulli, 2018
This work examines a class of switching jump diffusion processes. The main effort is devoted to proving the maximum principle and obtaining the Harnack inequalities.

A note on boundary point principles for partial differential inequalities of elliptic type

open access: yesBoundary Value Problems, 2022
In this note we consider boundary point principles for partial differential inequalities of elliptic type. First, we highlight the difference between the conditions required to establish classical strong maximum principles and classical boundary point ...

Maximum Principles and Aleksandrov-Bakelman-Pucci Type Estimates for NonLocal Schrödinger Equations with Exterior Conditions [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2017
We consider Dirichlet exterior value problems related to a class of non-local Schr\"odinger operators, whose kinetic terms are given in terms of Bernstein functions of the Laplacian.

Maximum principles in symplectic homology [PDF]

open access: yesIsrael Journal of Mathematics, 2017
In the setting of symplectic manifolds which are convex at infinity, we use a version of the Aleksandrov maximum principle to derive uniform estimates for Floer solutions that are valid for a wider class of Hamiltonians and almost complex structures than

Strong maximum principles for fractional Laplacians [PDF]

open access: yesProceedings of the Royal Society of Edinburgh: Section A Mathematics, 2016
We give a unified approach to strong maximum principles for a large class of nonlocal operators of order s ∈ (0, 1) that includes the Dirichlet, the Neumann Restricted (or Regional) and the Neumann Semirestricted Laplacians.

Singular limit of an activator-inhibitor type model

open access: yesNetworks and Heterogeneous Media, 2012
We consider a reaction-diffusion system of activator-inhibitor type arising in the theory of phase transition. Itappears in biological contexts such as pattern formation in population genetics.

On Korenblum’s maximum principle [PDF]

open access: yesProceedings of the American Mathematical Society, 1997
Summary: If \(f\) and \(g\) are analytic functions in the unit disk and \(|\cdot|\) is the Bergman norm, conditions are studied under which there exists an absolute constant \(c\) such that \(|f(z)|\geq|g(z)|\) for \(c\leq|z|
