A geometric approximation of non-local interface and boundary conditions

Pavel Exner, Andrii Khrabustovskyi

We analyze an approximation of a Laplacian subject to non-local interface conditions of a -type by Neumann Laplacians on a family of Riemannian manifolds with a sieve-like stru…

Quasinormal Ringing and Shadows of Black Holes and Wormholes in Dark Matter-Inspired Weyl Gravity

Roman A. Konoplya, Andrii Khrabustovskyi, Jan Kříž +1

Weyl gravity naturally generates effective dark matter and cosmological constant terms as integration constants, eliminating the need to explicitly introduce them into the theory.…
