Quantum field theory and Hopf algebra cohomology
Christian Brouder, Bertfried Fauser, Alessandra Frabetti +1
We exhibit a Hopf superalgebra structure of the algebra of field operators of quantum field theory (QFT) with the normal product. Based on this we construct the operator product an…

Noncommutative renormalization for massless QED
Christian Brouder, Alessandra Frabetti
We study the renormalization of massless QED from the point of view of the Hopf algebra discovered by D. Kreimer. For QED, we describe a Hopf algebra of renormalization which is ne…
