$\mathrm{SO}(3)$–Donaldson invariants of $\mathbb{C}\mathrm{P}^2$ and mock theta functions

Andreas Malmendier and Ken Ono

Geometry & Topology 16 (2012) 1767–1833
Abstract

We compute the Moore–Witten regularized u–plane integral on P2, and we confirm the conjecture that it is the generating function for the SO(3)–Donaldson invariants of P2. We also derive generating functions for the SO(3)–Donaldson invariants with 2Nf massless monopoles using the geometry of certain rational elliptic surfaces (Nf {0,2,3,4}), and we show that the partition function for Nf = 4 is nearly modular. Our results rely heavily on the theory of mock theta functions and harmonic Maass forms (for example, see Ono [Current developments in mathematics, 2008, Int. Press, Somerville, MA (2009) 347–454]).
