Some comments on the Hamiltonian for Unimodular Gravity
Enrique Álvarez, Jesús Anero
Several alternative formulations of the first order approach to unimodular gravity are presented. There is always a particular one such that it is {\em classically} equivalent to t…

Effective action in elliptic and hyperbolic spacetimes
Enrique Alvarez, Jesus Anero
The full one-loop (scalar) effective action is computed for both hyperbolic and elliptic spacetimes.
