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.

Maximum principles for parabolic systems coupled in both first-order and zero-order terms

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
Some generalized maximum principles are established for linear second-order parabolic systems in which both first-order and zero-order terms are coupled.

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 ...

Finite volume schemes for diffusion equations: introduction to and review of modern methods [PDF]

open access: yes, 2014
We present Finite Volume methods for diffusion equations on generic meshes, that received important coverage in the last decade or so. After introducing the main ideas and construction principles of the methods, we review some literature results ...

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

New maximum principles for linear elliptic equations

open access: yes, 2006
We prove extensions of the estimates of Aleksandrov and Bakel$'$man for linear elliptic operators in Euclidean space $\Bbb{R}^{\it n}$ to inhomogeneous terms in $L^q$ spaces for $q < n$.

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.

Enforcing the non-negativity constraint and maximum principles for diffusion with decay on general computational grids [PDF]

open access: yes, 2010
In this paper, we consider anisotropic diffusion with decay, and the diffusivity coefficient to be a second-order symmetric and positive definite tensor.

A Liouville type theorem for a class of anisotropic equations

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016
In this paper we are dealing with entire solutions of a general class of anisotropic equations. Under some appropriate conditions on the data, we show that the corresponding equations cannot have non-trivial positive solutions bounded from above.

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|
