Three dimensional gravity models with torsion and nonmetricity and the construction of their Chern-Simons theories
Abstract:
It is well known that 2+1 gravity can be formulated as a gauge theory
with Chern-Simons action. A generalization of general relatitvity is achieved
allowing the connection to posses torsion and nonmetricity. This is equivalent
to say that the underlying group is no more the Poincare group ISO(1,D-1)
but something more general. It will be shown that also for such models
of gravity with torsion and nonmetricity a Chern Simons-Formulation can
be obtained.
