Abstract: Polynomials are powerful tools in many fields, for example, representation theory, geometry, and topology. Understanding the combinatorics of the polynomials may reveal important information in these fields. This talk will focus on four polynomials from Schubert calculus: Schubert, key, Grothendieck, and Lascoux polynomials. I will discuss diagrams related to these polynomials, including Kohnert diagrams, snow diagrams, and rook diagrams. This is joint work with Tianyi Yu.
