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…

The spectrum and isometric embeddings of surfaces of revolution
Martin Engman
An upper bound on the first S^1 invariant eigenvalue of the Laplacian for invariant metrics on the 2-sphere is used to find obstructions to the existence of isometric embeddings of…
