Green’s Functions for Neumann Boundary Conditions

open access: yesMathematics
Green’s functions for Neumann boundary conditions have been considered in Math, Physics, and Electromagnetism textbooks, but often with mistakes of omission and commission. Special constraints and other properties required for Neumann boundary conditions

Nonlocal Neumann boundary conditions

open access: yesBruno Pini Mathematical Analysis Seminar, 2023
We present some properties of a nonlocal version of the Neumann boundary conditions associated to problems involving the fractional p-Laplacian. For this problems, we show some regularity results for the general case and some existence results for ...

Nonlocal problems with Neumann boundary conditions [PDF]

open access: yesRevista Matemática Iberoamericana, 2017
We introduce a new Neumann problem for the fractional Laplacian arising from a simple probabilistic consideration, and we discuss the basic properties of this model. We can consider both elliptic and parabolic equations in any domain. In addition, we formulate problems with nonhomogeneous Neumann conditions, and also with mixed Dirichlet and Neumann ...

Nonlocal Mixed Systems With Neumann Boundary Conditions [PDF]

open access: yesMathematical Methods in the Applied Sciences
ABSTRACTWe prove well posedness and stability in for a class of mixed hyperbolic–parabolic nonlinear and nonlocal equations in a bounded domain with no flow along the boundary. While the treatment of boundary conditions for the hyperbolic equation is standard, the extension to of classical results about parabolic equations with Neumann conditions ...

The Bose Gas in a Box with Neumann Boundary Conditions

open access: yesAnnales Henri Poincaré, 2023
We consider a gas of bosonic particles confined in a box with Neumann boundary conditions. We prove Bose-Einstein condensation in the Gross-Pitaevskii regime, with an optimal bound on the condensate depletion. Our lower bound for the ground state energy in the box implies (via Neumann bracketing) a lower bound for the ground state energy of the Bose ...

Isospectral shapes with Neumann and alternating boundary conditions [PDF]

open access: yesPhysical Review E, 2003
The isospectrality of a well-known pair of shapes constructed from two arrangements of seven congruent right isosceles triangles with the Neumann boundary condition is verified numerically to high precision. Equally strong numerical evidence for isospectrality is presented for the eigenvalues of this standard pair in new boundary configurations with ...

Order parameter profiles in a system with Neumann – Neumann boundary conditions

open access: yesMATEC Web of Conferences, 2018
In this article we consider a critical thermodynamic system with the shape of a thin film confined between two parallel planes. It is assumed that the state of the system at a given temperature and external ordering field is described by order-parameter ...

A Fast Algorithm for Deblurring Models with Neumann Boundary Conditions [PDF]

open access: yesSIAM Journal on Scientific Computing, 1999
The authors deal with the blur removal which is a fundamental issue in signal and image processing. They consider the use of the Neumann boundary conditions which are corresponding to a reflection of the original scene at the boundary. In this case the resulting matrices are (block) Toeplitz-plus-Hankel matrices. It is shown that for symmetric blurring
