Dirichlet Duality and the Nonlinear Dirichlet Problem [PDF]

open access: yesCommunications on Pure and Applied Mathematics, 2007
We study the Dirichlet problem for fully nonlinear, degenerate elliptic equations of the form f(Hess, u)=0 on a smoothly bounded domain D in R^n. In our approach the equation is replaced by a subset F of the space of symmetric nxn-matrices, with bdy(F ...

Infinite dimension of solutions of the Dirichlet problem

open access: yesOpen Mathematics, 2015
It is proved that the space of solutions of the Dirichlet problem for the harmonic functions in the unit disk with nontangential boundary limits 0 a.e. has the infinite dimension.

A Dirichlet problem in the strip

open access: yesElectronic Journal of Differential Equations, 1996
In this paper we investigate a Dirichlet problem in a strip and, using the sliding method, we prove monotonicity for positive and bounded solutions. We obtain uniqueness of the solution and show that this solution is a function of only one variable. From

The Dirichlet problem for nonlocal operators [PDF]

open access: yesMathematische Zeitschrift, 2014
In this note we set up the elliptic and the parabolic Dirichlet problem for linear nonlocal operators. As opposed to the classical case of second order differential operators, here the "boundary data" are prescribed on the complement of a given bounded set.

Solving a Dirichlet problem on unbounded domains via a conformal transformation [PDF]

open access: yesMathematische Annalen, 2022
In this paper, we solve the p-Dirichlet problem for Besov boundary data on unbounded uniform domains with bounded boundaries when the domain is equipped with a doubling measure satisfying a Poincaré inequality. This is accomplished by studying a class of

The Cauchy–Dirichlet problem for the Moore–Gibson–Thompson equation [PDF]

open access: yesComptes rendus. Mathematique, 2020
The Cauchy-Dirichlet problem for the Moore-Gibson-Thompson equation is analyzed. With the focus on non-homogeneous boundary data, two approaches are offered: one is based on the theory of hyperbolic systems, while the other one uses the theory of ...

On Green’s Function of the Dirichlet Problem for the Polyharmonic Equation in the Ball

open access: yesAxioms, 2023
The paper gives an explicit representation of the Green’s function of the Dirichlet boundary value problem for the polyharmonic equation in the unit ball. The solution of the homogeneous Dirichlet problem is found.

Existence of radial solutions for a p ( x ) $p(x)$ -Laplacian Dirichlet problem

open access: yesAdvances in Differential Equations, 2021
In this paper, using variational methods, we prove the existence of at least one positive radial solution for the generalized p ( x ) $p(x)$ -Laplacian problem − Δ p ( x ) u + R ( x ) u p ( x ) − 2 u = a ( x ) | u | q ( x ) − 2 u − b ( x ) | u | r ( x ) −

Parabolic and elliptic equations with singular or degenerate coefficients: The Dirichlet problem [PDF]

open access: yes, 2020
We consider the Dirichlet problem for a class of elliptic and parabolic equations in the upper-half space $\mathbb{R}^d_+$, where the coefficients are the product of $x_d^\alpha, \alpha \in (-\infty, 1),$ and a bounded uniformly elliptic matrix of ...

Higher order Nevanlinna functions and the inverse three spectra problem [PDF]

open access: yesOpuscula Mathematica, 2016
The three spectra problem of recovering the Sturm-Liouville equation by the spectrum of the Dirichlet-Dirichlet boundary value problem on \([0,a]\), the Dirichlet-Dirichlet problem on \([0,a/2]\) and the Neumann-Dirichlet problem on \([a/2,a]\) is ...
