Gromov-Witten invariants via algebraic geometry

Research output: Contribution to journalArticlepeer-review


Calculations of the number of curves on a Calabi-Yau manifold via an instanton expansion do not always agree with what one would expect naively. It is explained how to account for continuous families of instantons via deformation theory and excess intersection theory. The essential role played by degenerate instantons is also explained.
