Noether Identities and Gauge-Fixing the Action for Cosmological Perturbations
Macarena Lagos, Máximo Bañados, Pedro G. Ferreira +1
We propose and develop a general algorithm for finding the action for cosmological perturbations which rivals the conventional, gauge-invariant approach and can be applied to theor…

Behavior of perturbations on spherically symmetric backgrounds in multi-Galileon theory
Sebastian Garcia-Saenz
We consider multi-Galileon theory, the most general Galilean invariant theory with scalar fields linearly coupled to the trace of the stress-energy tensor. We study the behavio…
