Finiteness of the EPRL/FK spin foam model [PDF]

finite by dividing the vertex amplitude with an appropriate power $p$ of the
product of dimensions of the vertex spins. This power is independent of the
spin foam 2-complex and we find a lower bound for $p$ which makes the state sum
absolutely convergent.
