DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ZAG/189/">Ho
 lomorphic anomaly equations for the Hilbert schemes of points of a K3 surf
 ace</a>\nby Georg Oberdieck (Hausdorff Center for Mathematics) as part of 
 ZAG (Zoom Algebraic Geometry) seminar\n\n\nAbstract\nHolomorphic anomaly e
 quations are certain structural properties predicted by physics for the Gr
 omov-Witten theory of Calabi-Yau manifolds. In this talk I will explain th
 e conjectural form of these equations for the Hilbert scheme of points of 
 a K3 surface\, and explain how to prove them for genus 0 and up to three m
 arkings. As a corollary\, for fixed n\, the (reduced) quantum cohomology o
 f Hilb^n K3 is determined up to finitely many coefficients.\n
