Vacuum degeneracy in massive gravity: Multiplicity of fundamental scales
The presence of Nambu–Goldstone bosons introduce a natural degeneracy inside the
vacuum solutions of the nonlinear formulations of massive gravity in the same spirit of the σ-
models. When the gravitational effects are taken into account, and the observers are located
at any distance with respect to the source, this degeneracy corresponds to a multiplicity
(flow) of the fundamental scales of the theory. The different values of the fundamental scales
are connected to each other through the broken generators of the theory.
