SUMMARY:Algebraic Combinatorics - Michael Borinsky
CLASS:PUBLIC
DESCRIPTION:TITLE: Asymptotics of the Euler characteristic of\nKontsevich'
 s commutative graph complex\n\nSpeaker:\n Michael Borinsky\n\nAffiliation
 :\n ETH\, Zurich\n\nLocation:\n MC 5479 or contact Olya Mandelshtam for Zo
 om link\n\nABSTRACT: I will present results on the asymptotic growth rate
  of\nthe Euler characteristic of Kontsevich's commutative graph complex.\
 nBy a work of Chan-Galatius-Payne\, these results imply the same\nasympto
 tic growth rate for the top-weight Euler characteristic of\nM_g\, the mod
 uli \nspace of curves\, and establish the existence of large amounts\nof
  unexplained cohomology in this space. This asymptotic growth\nrate \nfo
 llows from new generating functions for the edge-alternating sum of\ngrap
 hs without odd automorphisms. I will give an overview on this \ninteracti
 on between topology and combinatorics and illustrate\nthe combinatorial a
 nd analytical tools that were needed to obtain\nthese \ngenerating functi
 ons.
