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…
La renormalisation dans la theorie non commutative des champs
Razvan Gurau
Non commutative quantum field theory is a possible candidate for the quantization of gravity. In our thesis we study in detail the model on the Moyal plane with an harmonic po…
Exorcizing the Landau Ghost in Non Commutative Quantum Field Theory
Razvan Gurau
We show that the simplest non commutative renormalizable field theory, the model on four dimensional Moyal space with harmonic potential is asymptotically safe to all orders…
Non-Commutative Complete Mellin Representation for Feynman Amplitudes
R. Gurau, A. P. C. Malbouisson, V. Rivasseau +1
We extend the complete Mellin (CM) representation of Feynman amplitudes to the non-commutative quantum field theories. This representation is a versatile tool. It provides a quick…
Vanishing of Beta Function of Non Commutative Theory to all orders
M. Disertori, R. Gurau, J. Magnen +1
The simplest non commutative renormalizable field theory, the model on four dimensional Moyal space with harmonic potential is asymptotically safe up to three loops, as shown…
