Schwinger-Dyson Equations in Group Field Theories of Quantum Gravity
Thomas Krajewski
In this talk, we elaborate on the operation of graph contraction introduced by Gurau in his study of the Schwinger-Dyson equations. After a brief review of colored tensor models, w…

Group field theories
Thomas Krajewski
Group field theories are particular quantum field theories defined on D copies of a group which reproduce spin foam amplitudes on a space-time of dimension D. In these lecture note…
