DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CJCS/74/">An
 ti-Ramsey theory\, lattice points on polytopes\, and Hodge structures on t
 oric hypersurfaces</a>\nby Soohyun Park (University of Chicago) as part of
  Copenhagen-Jerusalem Combinatorics Seminar\n\n\nAbstract\nThe relation be
 tween the topics in the title is obtained by combining combinatorial inter
 pretations of the simplicial chromatic polynomial. A reinterpretation of t
 he definition yields the connection to edge colorings of graphs avoiding m
 onochromatic colorings of specified subgraphs. As for lattice point counts
  on polytopes and Hodge structures on toric hypersurfaces\, we specialize 
 an expression of the polynomial in terms of the h-vector of an auxiliary s
 implicial complex.\n
