DESCRIPTION:Title: Elena Hafner\, University of Washington\n\nAbstract: Cas
 telnuovo-Mumford polynomials are the maximal degree components of Grothend
 ieck polynomials.  The support of each Castelnuovo-Mumford polynomial is c
 onjectured to be M-convex\, i.e. the set of integer points of a generalize
 d permutahedron (Mészáros and St. Dizier\, 2020).  This conjecture is know
 n to hold in certain special cases but remains open in general. We define 
 new families of permutations whose Castelnuovo-Mumford polynomials we show
  to have M-convex support.  Specifically\, we investigate which permutatio
 ns have Castelnuovo-Mumford polynomials whose supports are the set of inte
 ger points in a schubitope.\n\nRoom PK-4323 of UQAM’s Président-Kennedy Bu
 ilding.\n
