From the introduction: Let \(X\) be a nonsingular projective variety over \(\mathbb{C}\). Gromov-Witten theory concerns integration over \(\overline M_{g,n}(X,\beta)\), the moduli space of stable maps from genus \(g\), \(n\)-pointed curves to \(X\) representing the class \(\beta\in H_2(X, \mathbb{Z})\). While substantial progress in the mathematical study of Gromov-Witten theory has been made in the past decade several fundamental questions remain open.
The present author describes three conjectural directions: Gorenstein properties of tautological rings, BPS states for threefolds, Virasoro constraints. Each points to basic structures in Gromov-Witten theory which are not yet understood. New ideas in the subject will be required for answers to these questions.
For the entire collection see [Zbl 0993.00022].
