Spectral Geometry of Cosmological and Event Horizons for Kerr-Newman de Sitter metrics
Martin Engman, Gerardo A. Santana
We study the Laplace spectra of the intrinsic instantaneous metrics on the event and cosmological horizons of a Kerr-Newman de Sitter space-time and prove that the spectral data fr…

Intrinsic Spectral Geometry of the Kerr-Newman Event Horizon
Martin Engman, Ricardo Cordero Soto
We uniquely and explicitly reconstruct the instantaneous intrinsic metric of the Kerr-Newman Event Horizon from the spectrum of its Laplacian. In the process we find that the angul…
