HOMFLY invariants of algebraic links
Abstract: By intersecting a small three-dimensional sphere which surrounds a singular point
of a planar curve, with the curve, one obtains a link in three-dimensional space.
In my talk I explain a conjectural formula for the HOMFLY polynomial of the
link which interprets the polynomial in terms of topology of some natural stratification
on the moduli space of torsion free sheaves on the curve. The talk presents
joint work with Vivek Shende.
