Perverse Sheaves
Wintersemester 2013/14
In this Seminar we shall treat the sheaf theoretic theory of the intersection homology and its applications.
Program: we are going to discuss the following topics
- Intersection cohomology via chains
- Sheaf theoretic definition of intersection homology after Deligne
- L2 cohomology and intersection homology
- Intersection homology and topology of the Hilbert scheme of points
- Equivariant derived category of constructible sheaves
Time: Monday 10.00 - 11.30, UR2 (former SR3) of the Mathematical Institute.
