SUMMARY:Algebraic Combinatorics - Karen Yeats
CLASS:PUBLIC
DESCRIPTION:TITLE: Poset subHopf algebras from growth models in causal set\
 ntheory and quantum field theory\n\nSPEAKER:\n Karen Yeats\n\nAFFILIATION
 :\n University of Waterloo\n\nLOCATION:\n MC 5501 and Zoom - please contac
 t Oliver Pechenik for the Zoom\nlink\n\nABSTRACT: In a story some of you
  have heard from me before\, we get\nsubHopf algebras of the Connes-Kreime
 r Hopf algebra of rooted trees\nfrom certain simple tree classes which cor
 respond to solutions to\ncombinatorial analogues of Dyson-Schwinger equati
 ons in quantum field\ntheory.  Another important subHopf algebra of the C
 onnes-Kreimer Hopf\nalgebra is the Connes-Moscovici Hopf algebra which can
  be viewed as\ncoming from rooted trees grown by adding leaves.
