Hairy black holes in AdS with Robin boundary conditions [PDF]
Journal of High Energy Physics, 2023 We study hairy black holes in Einstein-Maxwell-complex scalar theory in four-dimensional asymptotically global anti-de Sitter (AdS) spacetime when the Robin boundary conditions are imposed on the scalar field.

Extremizing temperature functions of rods with Robin boundary conditions [PDF]
Annales Fennici Mathematici, 2022 We compare the solutions of two one-dimensional Poisson problems on an interval with Robin boundary conditions, one with given data, and one where the data has been symmetrized. When the Robin parameter is positive and the symmetrization is symmetric decreasing rearrangement, we prove that the solution to the symmetrized problem has larger increasing ...

Superradiance in the BTZ black hole with Robin boundary conditions [PDF]
Physics Letters B, 2018 We show the existence of superradiant modes of massive scalar fields propagating in BTZ black holes when certain Robin boundary conditions, which never include the commonly considered Dirichlet boundary conditions, are imposed at spatial infinity.

Entropy Solution for Doubly Nonlinear Elliptic Anisotropic Problems with Robin Boundary Conditions [PDF]
International Journal of Differential Equations, 2015 We study in this paper nonlinear anisotropic problems with Robin boundary conditions. We prove, by using the technic of monotone operators in Banach spaces, the existence of a sequence of weak solutions of approximation problems associated with the ...

Scalar field with Robin boundary conditions in the worldline formalism [PDF]
Journal of Physics A: Mathematical and Theoretical, 2008 The worldline formalism has been widely used to compute physical quantities in quantum field theory. However, applications of this formalism to quantum fields in the presence of boundaries have been studied only recently. In this article we show how to compute in the worldline approach the heat kernel expansion for a scalar field with boundary ...

Boundary dynamics and multiple reflection expansion for Robin boundary conditions [PDF]
, 2021 In the presence of a boundary interaction, Neumann boundary conditions should be modified to contain a function S of the boundary fields: (∇N + S) φ = 0.

Effect of Robin boundary conditions on the onset of convective torsional flows in rotating fluid spheres [PDF]
, 2023 Torsional flows are preferred at the onset of thermal convection in fluid spheres with stress-free and perfectly conducting boundary conditions, in a narrow region of the parameter space for Prandtl numbers Pr¿0.9 and ratios Pr/Ek=O(10)¿, with Ek being ...

On the p-Laplacian with Robin boundary conditions and boundary trace theorems [PDF]
Calculus of Variations and Partial Differential Equations, 2017 Let $Ω\subset\mathbb{R}^ν$, $ν\ge 2$, be a $C^{1,1}$ domain whose boundary $\partialΩ$ is either compact or behaves suitably at infinity. For $p\in(1,\infty)$ and $α>0$, define \[ Λ(Ω,p,α):=\inf_{\substack{u\in W^{1,p}(Ω)\\ u\not\equiv 0}}\dfrac{\displaystyle \int_Ω|\nabla u|^p \mathrm{d} x - α\displaystyle\int_{\partialΩ} |u|^p\mathrm{d}σ ...

Robin boundary conditions in shape optimization [PDF]
, 2015 The present thesis is concerned with the problem of proving the existence of optimal domains for functionals subjected to Robin Boundary conditions. We treat both cases of positive and negative Robin parameters. In the case of positive Robin parameters we prove the existence of a minimizing domain in a class of Lipschitz domains of given measure, that ...
