The Road to Stueckelberg's Covariant Perturbation Theory as Illustrated by Successive Treatments of Compton Scattering
J. Lacki, H. Ruegg, V. Telegdi
We review the history of the road to a manifestly covariant perturbative calculus within quantum electrodynamics from the early semi-classical results of the mid-twenties to the co…

Lattice Poincare as a quantum deformed algebra
Cesar Gomez, Henri Ruegg, Philippe Zaugg
We propose a definition of a Poincaré algebra for a two dimensional space--time with one discretized dimension. This algebra has the structure of a Hopf algebra. We use the link be…
