Schedule

Date Speaker Title
Jan 20 Peter McNamara (University of Melbourne) Sheaves behaving badly

This talk is about singularities of Schubert varieties, studied via sheaf-theoretic invariants like intersection cohomology and parity sheaves. The motivation comes from the use of these sheaves in representation theory, which began with the celebrated proof of the Kazhdan-Lusztig conjectures by Beilinson-Bernstein localisation. We will present examples of poor behaviour (in particular exhibit non-perverse parity sheaves), which thwart historic overly-optimistic conjectures on the singularities of Schubert varieties.
