Title: Intro to Schubert Calculus

Abstract: We will continue our discussion of the Schubert varieties and the cohomology ring of the Grassmannian. Schubert calculus is about computing the structure constants of this ring, which happen to be the Littlewood-Richardson numbers. We will recall methods we have seen so far for finding the Littlewood-Richardson numbers, as well as introducing a new way using puzzles. If time permits, we will extend our discussion to Schubert calculus in d-step flag varieties.
