|Title:||Three Hopf algebras and their common algebraic and categorical background|
|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.|
