Inflationary Cosmology as flow of integrable weights
Cesar Gomez
We identify the algebra of gauge invariant observables in de Sitter as the subalgebra of the type factor , associated to de Sitter, defined as the centralizer of an…
Duality and Black Hole Evaporation
Cesar Gomez
We construct a model that describes the quantum black hole evaporation unitarily in a Hilbert space of infinite dimension. This construction generalizes Page's finite dimensional a…
The Algebraic Page Curve
Cesar Gomez
The Page curve describing the process of black hole evaporation is derived in terms of a family, parametrized in terms of the evaporation time, of finite type II_1 factors, associa…
On the algebraic meaning of quantum gravity for closed Universes
Cesar Gomez
Assuming the von Neumann algebra associated with a generic de Sitter observer is properly infinite (type III) we use Connes cocycle to identify the unique ( up to unitary equivalen…
