Radiatively induced symmetry breaking and the conformally coupled magnetic monopole in AdS space
Ariel Edery, Noah Graham
We implement quantum corrections for a magnetic monopole in a classically conformally invariant theory containing gravity. This yields the trace (conformal) anomaly and introduces…
Reducing complexes in multidimensional persistent homology theory
Madjid Allili, Tomasz Kaczynski, Claudia Landi
The Discrete Morse Theory of Forman appeared to be useful for providing filtration-preserving reductions of complexes in the study of persistent homology. So far, the algorithms co…
Evolving black hole horizons in General Relativity and alternative gravity
Valerio Faraoni
From the microscopic point of view, realistic black holes are time-dependent and the teleological concept of event horizon fails. At present, the apparent or the trapping horizon s…
Conformally coupled inflation
Valerio Faraoni
A massive scalar field in a curved spacetime can propagate along the light cone, a causal pathology, which can, in principle, be eliminated only if the scalar couples conformally t…
