Nonlocal Neumann boundary conditions

Bruno 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 ...

Green’s Functions for Neumann Boundary Conditions

Mathematics
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

On p→(x)-Anisotropic Problems with Neumann Boundary Conditions

International Journal of Differential Equations, 2015
This work is devoted to the study of a general class of anisotropic problems involving p→(·)-Laplace operator. Based on the variational method, we establish the existence of a nontrivial solution without Ambrosetti-Rabinowitz type conditions.

Trace Formulae for Second-Order Differential Pencils with a Frozen Argument

Mathematics, 2023
This paper deals with second-order differential pencils with a fixed frozen argument on a finite interval. We obtain the trace formulae under four boundary conditions: Dirichlet–Dirichlet, Neumann–Neumann, Dirichlet–Neumann, Neumann–Dirichlet.

Free energy and defect C-theorem in free scalar theory

Journal of High Energy Physics, 2021
We describe conformal defects of p dimensions in a free scalar theory on a d-dimensional flat space as boundary conditions on the conformally flat space ℍ p+1 × 𝕊 d−p−1.

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

Advances 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.
