Title:Three Hopf algebras and their common algebraic and categorical background
Seminar:GAP Seminar
Speaker:Ralph Kaufman, IAS and Purdue University
We discsuss the renormalization Hopf algebra of Connes and Kreimer, Gontcharov's Hopf algebra for multi-zeta values and the Hopf algebra appearing in Baues' double cobar construction. We show that these are a examples of a common algebraic framework. Moreover this framework is a manifestation of one of the properties of Feynman categories, which we briefly define and discuss at the end.
