Anna Weigandt, University of Michigan, Gröbner Geometry of Schubert Polynomials Through Ice
ZoomSchubert calculus has its origins in enumerative questions asked by the geometers of the 19th century, such as "how many lines meet four fixed lines in three-space?" These problems can be recast as questions about the structure of cohomology rings of geometric spaces such as flag varieties. Borel's isomorphism identifies the cohomology of the complete…
