Title: Sequences of Trees and Higher-Order Renormalization Group Equations
Speaker: William Dugan Affiliation: University of Waterloo Room: MC 6483Abstract:
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.
