Newton Polytopes and Schubert Calculus

Schubert calculus studies the cohomology ring of the variety of complete flags. Many problems in Schubert calculus have meaningful implications in geometry and representation theory yet are amenable to combinatorial techniques. I will discuss striking classical applications of combinatorics to Schubert calculus, as well as some of my recent work on Newton polytopes of Schubert and Grothendieck polynomials. Joint work with Jack Chou.
