Klein Model for Hyperbolic Neural Networks
Yidan Mao, Jing Gu, Marcus C. Werner +1
Hyperbolic neural networks (HNNs) have been proved effective in modeling complex data structures. However, previous works mainly focused on the Poincaré ball model and the hyperbol…
Finsler pp-waves and the Penrose Limit
Amir Babak Aazami, Miguel Ángel Javaloyes, Marcus C. Werner
The Penrose plane wave limit is a remarkable property of Lorentzian spacetimes. Here, we discuss its extension to Finsler spacetimes by introducing suitable lightlike coordinates a…
Gravitational lensing in area metric spacetimes
Marcus C. Werner
We consider light propagation as a probe of non-metricity in area metric spacetimes, and find a deviation from the standard Etherington relation for linearized area metric Schwarzs…
The Struble-Einstein Correspondence
Marcus C. Werner
This article presents hitherto unpublished correspondence of Struble in 1947 with Menger, Chandrasekhar, and eventually Einstein, about a possible observational test supporting Ein…
Jacobi-Maupertuis Randers-Finsler metric for curved spaces and the gravitational magnetoelectric effect
Sumanto Chanda, G. W. Gibbons, Partha Guha +2
In this paper we return to the subject of Jacobi metrics for timelike and null geodsics in stationary spactimes, correcting some previous misconceptions. We show that not only null…
The gravitational magnetoelectric effect
Gary W. Gibbons, Marcus C. Werner
Electromagnetism in spacetime can be treated in terms of an analogue linear dielectric medium. In this paper, we discuss the gravitational analogue of the linear magnetoelectric ef…
