Modeling of Chloride Distribution in Cement-Based Materials with Neumann Boundary Condition [PDF]

open access: goldAdvances in Materials Science and Engineering, 2018
The nonstable transport of chloride in cement-based materials, including diffusion, convection, and chloride binding, is described as a general form of Fick’s law.

Neumann boundary condition for Abelian BPS vortices

open access: yesJournal of High Energy Physics, 2023
We study abelian BPS vortices on a surface S with boundary, which satisfy the Neumann boundary condition on the norm of the scalar field, or equivalently, that the current along the boundary vanishes.

Ambrosetti-Prodi problem with degenerate potential and Neumann boundary condition [PDF]

open access: greenElectronic Journal of Differential Equations, 2018
We study the degenerate elliptic equation $$ -\hbox{div}(|x|^\alpha\nabla u) =f(u)+t\phi(x)+h(x) $$ in a bounded open set $\Omega$ with homogeneous Neumann boundary condition, where $\alpha\in(0,2)$ and f has a linear growth.

Exact Null Controllability of a One-Dimensional Wave Equation with a Mixed Boundary

open access: yesMathematics, 2023
In this paper, exact null controllability of one-dimensional wave equations in non-cylindrical domains was discussed. It is different from past papers, as we consider boundary conditions for more complex cases.

On the ghost problem of conformal gravity

open access: yesJournal of High Energy Physics, 2023
We study the metric perturbations around the de Sitter and Minkowski backgrounds in Conformal Gravity. We confirm the presence of ghosts in both cases. In the de Sitter case, by applying the Maldacena boundary conditions — the Neumann boundary condition ...

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.

Free energy and defect C-theorem in free fermion

open access: yesJournal of High Energy Physics, 2021
We describe a p-dimensional conformal defect of a free Dirac fermion on a d-dimensional flat space as boundary conditions on a conformally equivalent space ℍ p+1 × S $$ \mathbbm{S} $$ d−p−1.

Boundary regularity results for minimisers of convex functionals with (p, q)-growth

open access: yesAdvances in Nonlinear Analysis, 2023
We prove improved differentiability results for relaxed minimisers of vectorial convex functionals with (p,q)\left(p,q)-growth, satisfying a Hölder-growth condition in xx. We consider both Dirichlet and Neumann boundary data.

The Meyers Estimates for Domains Perforated along the Boundary

open access: yesMathematics, 2021
In this paper, we consider an elliptic problem in a domain perforated along the boundary. By setting a homogeneous Dirichlet condition on the boundary of the cavities and a homogeneous Neumann condition on the outer boundary of the domain, we prove ...
