Title: Sequences of Trees and Higher-Order Renormalization Group Equations

Speaker: William Dugan Affiliation: University of Waterloo Room: MC 6483

Abstract:

In 1998, Connes and Kreimer introduced a combinatorial Hopf algebra HCK on the vector space of forests of rooted trees that precisely explains the phenomenon of renormalization in quantum eld theory.
