ON HYPERBOLIC-PARABOLIC PROBLEMS WITH INVOLUTION AND NEUMANN BOUNDARY CONDITION [PDF]

open access: diamondInternational Journal of Apllied Mathematics, 2021
: We study a nonlocal boundary value problem and a space-wise dependent source identification problem for one-dimensional hyperbolic-parabolic equation with involution and Neumann boundary condition.

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.

Two-phase eigenvalue problem on thin domains with Neumann boundary condition [PDF]

open access: greenDifferential and Integral Equations, 2017
In this paper, we study an eigenvalue problem with piecewise constant coefficients on thin domains with Neumann boundary condition, and we analyze the asymptotic behavior of each eigenvalue as the domain degenerates into a certain hypersurface being the ...

Entropy solutions for nonlinear elliptic anisotropic problems with homogeneous Neumann boundary condition

open access: hybrid, 2015
This study is about a nonlinear anisotropic problem with homogeneous Neumann boundary condition. We first prove, by using the technic of monotone operators in Banach spaces, the existence of weak solution, and by approximation methods, we achieve a ...

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.
