DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TGiZ/36/">Th
 e $S_n$ action on the homology groups of $\\overline{M}_{0\,n}$</a>\nby Ro
 hini Ramadas (University of Warwick) as part of Tropical Geometry in Frank
 furt/Zoom TGiF/Z\n\n\nAbstract\nThe symmetric group on $n$ letters acts on
  $\\overline{M}_{0\,n}$\, and thus on its (co-)homology groups. The induce
 d actions on (co-)homology have been studied by\, eg.\, Getzler\, Bergstro
 m-Minabe\, Castravet-Tevelev. We ask: does $H_{2k}(\\overline{M}_{0\,n})$ 
 admit an equivariant basis\, i.e. one that is permuted by $S_n$? We descri
 be progress towards answering this question. This talk includes joint work
  with Rob Silversmith.\n
