Canonical description of Pontryagin and Euler classes with a Barbero-Immirzi parameter

Alberto Escalante, Edmundo Suárez-Polo, Luis A. Huerta-del Campo

A detailed canonical analysis for Pontryagin and Euler classes with a Barbero-Immirzi [BI] parameter is developed. We rewrite the topological invariants by introducing a set of Hol…
