 | The 1/N Expansion in Random Tensor Models Speaker(s): Razvan Gurau
Abstract: Matrix models yield a theory of random two dimensional surfaces. They support a 1/N expansion dominated by planar graphs (corresponding to planar surfaces) and undergo a phase transition to a continuum theory. In higher dimensions matrix models generalize to tensor models. In the absence of a viable... read more

Renormalization in Noncommutative Quantum Field Theory Speaker(s): Razvan Gurau
Abstract: This talk presents some recent results in renormalizable noncommutative quantum field theory. After introducing the renormalization group approach in the commutative setting I will procede to its generalization to the simplest noncommutative model, $phi_4^{star 4}$ on the Moyal space. The well known... read more
