Ambient space and integration of the trace anomaly
Gregorio Paci, Omar Zanusso
We use the ambient space construction, in which spacetime is mapped into a special lightcone of a higher dimensional manifold, to derive the integrable terms of the trace anomaly i…

Euclidean actions and static black hole entropy in teleparallel theories
Iberê Kuntz, Gregorio Paci, Omar Zanusso
It is well-known that the results by Bekenstein, Gibbons and Hawking on the thermodynamics of black holes can be reproduced quite simply in the Euclidean path integral approach to…

Weyl cohomology and the conformal anomaly in the presence of torsion
Gregorio Paci, Omar Zanusso
Using cohomological methods, we identify both trivial and nontrivial contributions to the conformal anomaly in the presence of vectorial torsion in dimensions. In both case…
