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…

Combinatorial Hopf algebraic description of the multiscale renormalization in quantum field theory
Thomas Krajewski, Vincent Rivasseau, Adrian Tanasa
We define in this paper several Hopf algebras describing the combinatorics of the so-called multi-scale renormalization in quantum field theory. After a brief recall of the main ma…

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…
