Logarithmic Gromov-Witten Invariants

speaker: Dan Abramovich (Brown University)

abstract: Logarithmic Gromov-Witten invariants generalize relative Gromov-Witten invariants, which count curves on a variety satisfying certain tangency conditions. I will report on work of Qile Chen, Abramovich-Chen and Abramovich-Chen-Gillam-Marcus, and closely related work of Gross and Siebert. The main construction is that of logarithmic stable maps, proposed by Bernd Siebert in a 2001 lecture.
