Title: |
Parametrised group field theories and quantum gravity transition
amplitudes
|
| Abstract: |
We describe a generalisation of the group field theory formalism to
include extra variables with the interpretation of proper time, and an
action that contains derivative kinetic terms; we show how to construct
the Feynman expansion of the field theory and how to obtain both causal and
a-causal spin foam amplitudes from this generalised formalism.
