Tensor Field Theory: Renormalization and One-loop Beta Functions
Speaker(s): Joseph Ben Geloun
Abstract: Tensor models appear as the higher dimensional extension of the so-called matrix models describing 2D quantum gravity through the sum over triangulations of surfaces. In the light of the recent $1/N$ expansion for these tensor models, we uncover a new class of tensor models for 4D and 3D gravity whi... read more

Colored group field theory: Scaling properties and positivity
Speaker(s): Joseph Ben Geloun
Abstract: The scaling analysis in the large spin limit of Feynman amplitudes for the Bosonic colored group field theory are considered in any dimension starting with dimension 4. By an explicit integration of two colors, we show that the model is positive. This formulation could be useful for the constructive... read more
