No-Boundary Proposal as a Path Integral with Robin Boundary Conditions. [PDF]
Physical Review Letters, 2019 Realizing the no-boundary proposal of Hartle and Hawking as a consistent gravitational path integral has been a long-standing puzzle. In particular, it was demonstrated by Feldbrugge, Lehners, and Turok that the sum over all universes starting from a ...

The BFK type gluing formula of zeta-determinants for the Robin Boundary condition [PDF]
arXiv, 2023 In this paper we discuss the BFK type gluing formula for zeta-determinants of Laplacians with respect to the Robin boundary condition on a compact Riemannian manifold. As a special case, we discuss the gluing formula with respect to the Neumann boundary condition.

Vacuum polarization on topological black holes with Robin boundary conditions [PDF]
Physical Review D, 2020 We compute the renormalized vacuum polarization for a massless, conformally coupled scalar field on asymptotically anti--de Sitter black hole backgrounds. Mixed (Robin) boundary conditions are applied on the spacetime boundary.

Weber-Type Integral Transform Connected with Robin-Type Boundary Conditions
Mathematics, 2020 A new Weber-type integral transform and its inverse are defined for the representation of a function f(r,t), (r,t)∈[R,1]×[0,∞) that satisfies the Dirichlet and Robin-type boundary conditions f(R,t)=f1(t), f(1,t)−α∂f(r,t)∂r|r=1=f2(t), respectively.

Robin boundary conditions for the Laplacian on metric graph completions [PDF]
arXiv, 2021 A generalization of Robin boundary conditions leading to self-adjoint operators is developed for the second derivative operator on metric graphs with compact completion and totally disconnected boundary. Harmonic functions and their properties play an essential role.
arxiv
Electronic Journal of Qualitative Theory of Differential Equations, 2021 We focus on a system of two competing species with cross-diffusion and self-diffusion. By constructing an appropriate auxiliary function, we derive the sufficient conditions such that there are no coexisting steady-state solutions to the model.

AdS Robin solitons and their stability [PDF]
, 2020 We consider the four-dimensional Einstein-Klein-Gordon-AdS system with conformal mass subject to the Robin boundary conditions at infinity. Above a critical value of the Robin parameter, at which the AdS spacetime goes linearly unstable, we prove existence of a family of globally regular static solutions (that we call AdS Robin solitons) and discuss ...

Molecular Oncology, EarlyView.Large multidimensional digital images of cancer tissue are becoming prolific, but many challenges exist to automatically extract relevant information from them using computational tools. We describe publicly available resources that have been developed jointly by expert and non‐expert computational biologists working together during a virtual hackathon

On a singularly perturbed semi-linear problem with Robin boundary conditions
, 2021 This paper is concerned with a semi-linear elliptic problem with Robin boundary condition: \begin{document}$ \begin{equation} \left\{\begin{array}{lll} \varepsilon \Delta w-\lambda w^{1+\chi} = 0, &\text{in} \ \Omega\\ \nabla w \cdot \vec{n}+\gamma w = 0,
