On a free boundary value problem for the anisotropic N-Laplace operator on an N−dimensional ring domain

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020
In this paper we are going to investigate a free boundary value problem for the anisotropic N-Laplace operator on a ring domain Ω:=Ω0\Ω¯1⊂𝕉N\Omega : = {\Omega _0}\backslash {\bar \Omega _1} \subset {\mathbb{R}^N}, N ≥ 2.

The uniqueness of the solution for the definite problem of a parabolic variational inequality

open access: yesJournal of Inequalities and Applications, 2016
The uniqueness of the solution for the definite problem of a parabolic variational inequality is proved. The problem comes from the study of the optimal exercise strategies for the perpetual executive stock options with unrestricted exercise in financial

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.

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 ...

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.

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 ...

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 $q < n$.
