### Definition of n-point function in nonperturbative quantum gravity and low energy limit of the loop-spin foam formalism

Seminar Room 1, Newton Institute

#### Abstract

The boundary formulation of quantum field theory can be used to provide a background-independent definition of n-point function. The application of this idea to a tentative loop/spinfoam theory defined via group-field-theory methods leads to a two-point function that, at a preliminary analysis appears to be consistent with the propagator of general relativity, and therefore with the Newton law.
