Integrals of psi-classes over double ramification cycles
A. Buryak, S. Shadrin, L. Spitz +1
DR-cycles are certain cycles on the moduli space of curves. Intuitively, they parametrize curves that allow a map to \mathbb{P}^1 with some specified ramification profile over two…

Generating series of the Poincare polynomials of quasihomogeneous Hilbert schemes
A. Buryak, B. L. Feigin
In this paper we prove that the generating series of the Poincare polynomials of quasihomogeneous Hilbert schemes of points in the plane has a beautiful decomposition into an infin…
