Spectral Quadruples
Tomas Kopf, Mario Paschke
A set of data supposed to give possible axioms for spacetimes. It is hoped that such a proposal can serve to become a testing ground on the way to a general formulation. At the mom…
A Spectral Quadruple for de Sitter Space
T. Kopf, M. Paschke
A set of data supposed to give possible axioms for spacetimes with a sufficient number of isometries in spectral geometry is given. These data are shown to be sufficient to obtain…
Spectral geometry of spacetime
T. Kopf
Spacetime, understood as a globally hyperbolic manifold, may be characterized by spectral data using a 3+1 splitting into space and time, a description of space by spectral triples…
Spinorial density matrix equation and gauge covariance
F. C. Khanna, A. E. Santana, A. Matos Neto +2
In this work we apply the Lie group representation method introduced in the real time formalism for finite-temperature quantum-field theory, thermofield dynamics, to derive a spino…
Spectral Geometry and Causality
Tomas Kopf
For a physical interpretation of a theory of quantum gravity, it is necessary to recover classical spacetime, at least approximately. However, quantum gravity may eventually provid…
Too Soon for Doom Gloom?
Tomas Kopf, Pavel Krtous, Don N. Page
The observation that we are among the first 10^{11} or so humans reduces the prior probability that we find ourselves in a species whose total lifetime number of individuals is muc…
