Maximum Principles and Boundary Value Problems for First-Order Neutral Functional Differential Equations

open access: goldJournal of Inequalities and Applications, 2009
We obtain the maximum principles for the first-order neutral functional differential equation where , and are linear continuous operators, and are positive operators, is the space of continuous functions, and is the space of essentially ...

Strong maximum principles for implicit parabolic functional-differential problems together with initial inequalities

open access: greenAnnales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2004
The aim of the paper is to give strong maximum principles for implicit non-linear parabolic functional-differential problems together with initial inequalities in relatively arbitrary $(n+1)$-dimensional time - space sets more general than cylindrical ...

Principal eigenvalues for k-Hessian operators by maximum principle methods

open access: yesMathematics in Engineering, 2021
For fully nonlinear $k$-Hessian operators on bounded strictly $(k-1)$-convex domains $\Omega$ of $\R^N$, a characterization of the principal eigenvalue associated to a $k$-convex and negative principal eigenfunction will be given as the supremum over ...

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

Maximum Principles for Matrix-Valued Analytic Functions [PDF]

open access: yesThe American mathematical monthly, 2019
To what extent is the maximum modulus principle for scalar-valued analytic functions valid for matrix-valued analytic functions? In response, we discuss some maximum norm principles for such functions that do not appear to be widely known, deduce maximum
