Aspects of Group Field Theory
arXiv:1203.5679 · doi:10.1063/1.4733364
Abstract
I review the basic ingredients of discretized gravity which motivate the introduction of Group Field Theory. Thus I describe the GFT formulation of some models and conclude with a few remarks on the emergence of noncommutative structures in such models.
