Descripción
At this meeting we presented a spinfoam model in which the fundamental
"bubble amplitudes" (the analog of the one-loop corrections in QFT) are
finite as the cutoff is removed. The model is a natural variant of the
field theoretical formulation of the Barrett-Crane model. As the last,
the model is a quantum BF theory plus an implementation of the
constraint that reduces BF theory to GR. This motivated the conjecture
of finiteness of the model: all its Feynman diagrams converge. This
conjecture has now been proven.
