The Geometry of Grassmannians and Flag varieties
Abstract: A Littlewood-Richardson rule is a positive rule for computing
the structure constants of the cohomology ring of flag varieties with
respect to their Schubert basis. In recent years new geometric
Littlewood-Richardson rules have led to the solution of many important
problems, including Klyachko, Knutson and Tao's solution of Horn's
conjecture and Vakil's solution of the reality of Schubert calculus. In
this talk I will survey some of the basic geometric ideas that underlie
these Littlewood-Richardson rules.
