Research Seminar: "Grid Diagrams and Schubert varieties"
Fri, March 12, 2010 2:00PM - 3:00PM

| Location: | Simons Auditorium |
| Speakers: | Christian Kassel, Christian Kassel |
| Abstract: | Recently, Manulescu, Ozsváth, Sarkar, Szábo, D. Thurston gave a combinatorial construction of the Heegaard-Floer homology of links based on the presentation of links by "grid diagrams." I will show how grid diagrams can be used to solve a problem in a different area, namely the determination of the singular locus of a Schubert variety. My talk is based on joint work with Alain Lascoux and Christophe Reutenauer (J. of Algebra, 2003). |
