SUMMARY:Algebraic Combinatorics Seminar - Lukas Nabergall
CLASS:PUBLIC
DESCRIPTION:TITLE: Weighted generating functions for weighted chord diagra
 ms\n\nSpeaker:\n Lukas Nabergall\n\nAffiliation:\n University of Waterloo\
 n\nZoom:\n Contact Karen Yeats\n\nABSTRACT:\n\nMotivated by the universal 
 property of the Connes-Kreimer Hopf algebra\nof rooted trees and Hopf suba
 lgebras arising from so-called\ncombinatorial Dyson-Schwinger equations\, 
 we introduce a class of\ntwo-variable recursive functional equations invol
 ving Hochschild\n1-cocycle operators.
