The Ponzano-Regge asymptotic of the 6j symbol: an elementary proof
Razvan Gurau
In this paper we give a direct proof of the Ponzano-Regge asymptotic formula for the Wigner 6j symbol starting from Racah's single sum formula. Our method treats halfinteger and in…

A translation-invariant renormalizable non-commutative scalar model
R. Gurau, J. Magnen, V. Rivasseau +1
In this paper we propose a translation-invariant scalar model on the Moyal space. We prove that this model does not suffer from the UV/IR mixing and we establish its renormalizabil…
