Fano Varieties and Extremal Laurent Polynomials

Here are my notes from Kresch’s talk in Bonn:

Kresch_Bonn_Sep_2010

Summary:

• the orthogonal Grassmannian
• Schubert varieties are indexed by strict partitions
• special Schubert classes
• ring presentations for and
• the connection to algebraic combinatorics via Praguez-Rataiski polynomials
• quantum Giambelli and quantum Pieri (Kresch-Tamvarkis)
