Boundary unique continuation theorems under zero Neumann boundary conditions [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2005
Let u be a solution to a second order elliptic equation with singular potentials belonging to the Kato-Fefferman-Phong's class in Lipschitz domains. We prove the boundary unique continuation theorems and the doubling properties for u2 near the boundary under the zero Neumann boundary condition.

Tweaking one-loop determinants in AdS3

open access: yesJournal of High Energy Physics, 2017
We revisit the subject of one-loop determinants in AdS3 gravity via the quasi-normal mode method. Our goal is to evaluate a one-loop determinant with chiral boundary conditions for the metric field; chirality is achieved by imposing Dirichlet boundary ...

Boundary confining dualities and Askey-Wilson type q-beta integrals

open access: yesJournal of High Energy Physics, 2023
We propose confining dualities of N $$ \mathcal{N} $$ = (0, 2) half-BPS boundary conditions in 3d N $$ \mathcal{N} $$ = 2 supersymmetric SU(N), USp(2n) and SO(N) gauge theories.

Meningovascular Inflammation in Cerebral Amyloid Angiopathy‐Related Cortical Superficial Siderosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT The role of inflammation in cortical superficial siderosis (cSS), a marker of cerebral amyloid angiopathy (CAA) linked to high hemorrhage risk, is unclear. We examined 15 patients with cSS using 3 T post‐contrast vessel wall MRI (VWI) and CSF analysis.

A Neumann Boundary Term for Gravity

open access: yes, 2017
The Gibbons-Hawking-York (GHY) boundary term makes the Dirichlet problem for gravity well defined, but no such general term seems to be known for Neumann boundary conditions. In this paper, we view Neumann {\em not} as fixing the normal derivative of the

Impact of Pre‐Oxidation Treatments on a Recycled MgO/Steel‐Composite as Carbon Free Anode in Aluminum‐Electrolysis Environments

open access: yesAdvanced Engineering Materials, EarlyView.
Cermets (60 vol.% AISI 316L stainless steel, 40 vol.% recycled MgO), intended for use in aluminum electrolysis, were pre‐oxidized in three furnaces with different heating technologies and subjected to a cryolite corrosion test. The different atmospheres influenced the formation of oxide layers, which in turn affected corrosion resistance and ...

Computational approaches to initial-boundary value problems with Neumann boundary conditions

open access: yesJournal of Taibah University for Science, 2018
In this paper, recursive solution schemes for different boundary value problems and initial-boundary value problems of partial differential equations with Neumann boundary conditions are proposed.

Pointwise observation of the state given by complex time lag parabolic system

open access: yesArchives of Control Sciences, 2017
Various optimization problems for linear parabolic systems with multiple constant time lags are considered. In this paper, we consider an optimal distributed control problem for a linear complex parabolic system in which different multiple constant time ...

On the dynamics in the AdS/BCFT correspondence

open access: yesJournal of High Energy Physics, 2022
We consider a perturbation of the Einstein gravity with the Neumann boundary condition, which is regarded as an end of the world brane (ETW brane) of the AdS/BCFT correspondence, in the AdS d+1 spacetime with d ≥ 3.

Vacuum Energy and Renormalization on the Edge

open access: yes, 2007
The vacuum dependence on boundary conditions in quantum field theories is analysed from a very general viewpoint. From this perspective the renormalization prescriptions not only imply the renormalization of the couplings of the theory in the bulk but ...
