Topological Graph Polynomials and Quantum Field Theory, Part I: Heat Kernel Theories
T. Krajewski, V. Rivasseau, A. Tanasa +1
We investigate the relationship between the universal topological polynomials for graphs in mathematics and the parametric representation of Feynman amplitudes in quantum field the…
Wilsonian renormalization, differential equations and Hopf algebras
Thomas Krajewski, Pierre Martinetti
In this paper, we present an algebraic formalism inspired by Butcher's B-series in numerical analysis and the Connes-Kreimer approach to perturbative renormalization. We first defi…
Seesaw and noncommutative geometry
J. -H. Jureit, Thomas Krajewski, Thomas Schucker +1
The 1-loop corrections to the seesaw mechanism in the noncommutative standard model are computed. Other consequences of the Lorentzian signature in the inner space are summarised.
