Cosmological signature change in Cartan Gravity with dynamical symmetry breaking
Joao Magueijo, Matias Rodriguez-Vazquez, Hans Westman +1
We investigate the possibility for classical metric signature change in a straightforward generalization of the first order formulation of gravity, dubbed "Cartan gravity". The mat…

Exploring Cartan gravity with dynamical symmetry breaking
H. F. Westman, T. G. Zlosnik
It has been known for some time that General Relativity can be regarded as a Yang-Mills-type gauge theory in a symmetry broken phase. In this picture the gravity sector is describe…
