The degeneration formula for stable log maps

Algebraic Geometry 2021-11-23 v2 Symplectic Geometry

Abstract

We give a short direct proof for the degeneration formula of Gromov-Witten invariants including its cycle version for degenerations with smooth singular locus in the setting of minimal/basic stable log maps of Abramovich-Chen, Chen, Gross-Siebert.
