Fick’s law selects the Neumann boundary condition

open access: yesNonlinear Analysis, 2023
We study the appearance of a boundary condition along an interface between two regions, one with constant diffusivity $1$ and the other with diffusivity $\eps>0$, when $\eps\to0$.

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.

Least gradient problems with Neumann boundary condition [PDF]

open access: yesJournal of Differential Equations, 2016
We study existence of minimizers of the least gradient problem inf v ∈ B V g ⁡ ∫ Ω φ ( x , D v ) , where B V g = { v ∈ B V ( Ω ) : ∫ ∂ Ω g v = 1 } , φ ( x , p ) : Ω × R n → R is a convex, continuous, and homogeneous function of degree 1 with respect to ...

Identification hyperbolic problems with the Neumann boundary condition

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2018
In the present study, an identification problem with the Neumann boundary condition for a one-dimensional hyperbolic equation is investigated. Stability estimates for the solution of the identification problem are established. Furthermore, a first order

On a waveguide with frequently alternating boundary conditions: homogenized Neumann condition [PDF]

open access: yesAnnales Henri Poincaré, 2010
We consider a waveguide modeled by the Laplacian in a straight planar strip. The Dirichlet boundary condition is taken on the upper boundary, while on the lower boundary we impose periodically alternating Dirichlet and Neumann condition assuming the ...

Level-set forced mean curvature flow with the Neumann boundary condition [PDF]

open access: yesJournal des Mathématiques Pures et Appliquées, 2021
. Here, we study a level-set forced mean curvature flow with the homogeneous Neumann boundary condition. We first show that the solution is Lipschitz in time and locally Lipschitz in space.

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.
