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…

On the Leibniz cohomology of vector fields
Alessandra Frabetti, Friedrich Wagemann
I. M. Gelfand and D. B. Fuks have studied the cohomology of the Lie algebra of vector fields on a manifold. In this article, we generalize their main tools to compute the Leibniz c…
