Quasi-Linear Relaxed Dirichlet Problems

SIAM Journal on Mathematical Analysis, 1996
This work is devoted to the study of quasilinear relaxed Dirichlet problems that can ``formally'' be written as \[ -\Delta u+\lambda_0u+\mu u= f(x,u,Du)\quad\text{in }\Omega,\quad u=0\quad\text{on }\partial\Omega, \] where \(\Omega\) is a bounded domain in \(\mathbb{R}^n\), \(\lambda_0\geq 0\), \(f\) satisfies a quadratic growth condition with respect ...

Relaxation for Dirichlet Problems Involving a Dirichlet Form

Zeitschrift für Analysis und ihre Anwendungen, 2000
For a fixed Dirichlet form, we study the space of positive Borel measures (possibly infinite) which do not charge polar sets. We prove the density in this space of the set of the measures which represent varying, domains. Our method is constructive. For the Laplace operator, the proof was based on a pavage of the space.

Exterior Dirichlet Problem

2020
The exterior Dirichlet problem consists in finding u such that $$\displaystyle \begin {array}{rl} &Au(x)=0,\quad x\in S^-,\\ &u(x)=\mathscr {D}(x),\quad x\in {\partial S},\\ &u\in \mathscr {A}^*, \end {array} $$ where the vector function \(\mathscr {D}\in C^{(1,\alpha )}({\partial S})\), α ∈ (0, 1), is prescribed.

Interior Dirichlet Problem

2020
The interior Dirichlet problem consists of the equation and boundary condition $$\displaystyle \begin {array}{ll} &Au(x)=0,\quad x\in S^+,\\ &u(x)=\mathscr {D}(x),\quad x\in {\partial S}, \end {array} $$ where the vector function \(\mathscr {D}\in C^{1,\alpha }({\partial S})\), α ∈ (0, 1), is prescribed.

The Dirichlet Problem

2001
In its simplest form the Dirichlet problem may be stated as follows: for a given function \( f \in C\left( {{\partial ^\infty }\Omega } \right)\), determine, if possible, a function h ∈ H(Ω) such that h(x) → f(y) as x → y for each \( y \in {\partial ^\infty }\Omega \).
