Enforcing Dirichlet boundary conditions in physics-informed neural networks and variational physics-informed neural networks [PDF]

open access: yesHeliyon, 2023
In this paper, we present and compare four methods to enforce Dirichlet boundary conditions in Physics-Informed Neural Networks (PINNs) and Variational Physics-Informed Neural Networks (VPINNs).

Quantum “violation” of Dirichlet boundary condition

open access: yesPhysics Letters B, 2017
Dirichlet boundary conditions have been widely used in general relativity. They seem at odds with the holographic property of gravity simply because a boundary configuration can be varying and dynamic instead of dying out as required by the conditions ...

Consistent dirichlet boundary conditions for numerical solution of moving boundary problems [PDF]

open access: yesApplied Numerical Mathematics, 2008
We consider the imposition of Dirichlet boundary conditions in the finite element mod-elling of moving boundary problems in one and two dimensions for which the total mass is prescribed.

Trace Formulae for Second-Order Differential Pencils with a Frozen Argument

open access: yesMathematics, 2023
This paper deals with second-order differential pencils with a fixed frozen argument on a finite interval. We obtain the trace formulae under four boundary conditions: Dirichlet–Dirichlet, Neumann–Neumann, Dirichlet–Neumann, Neumann–Dirichlet.

Free energy and defect C-theorem in free scalar theory

open access: yesJournal of High Energy Physics, 2021
We describe conformal defects of p dimensions in a free scalar theory on a d-dimensional flat space as boundary conditions on the conformally flat space ℍ p+1 × 𝕊 d−p−1.

Singular elliptic problems with Dirichlet or mixed Dirichlet-Neumann non-homogeneous boundary conditions [PDF]

open access: yesOpuscula Mathematica, 2022
Let \(\Omega\) be a \(C^{2}\) bounded domain in \(\mathbb{R}^{n}\) such that \(\partial\Omega=\Gamma_{1}\cup\Gamma_{2}\), where \(\Gamma_{1}\) and \(\Gamma_{2}\) are disjoint closed subsets of \(\partial\Omega\), and consider the problem\(-\Delta u=g ...
