Abstract
Let $X$ be a non-singular projective variety. Gromov--Witten (GW) theory is a way of counting curves in $X$ and it is a fundamental fact that the resulting numbers are invariant under deformations of $X$. Logarithmic GW theory is a deformation-invariant extension of GW theory to spaces having mild (e.g., normal crossings) singularities. I will explain two distinct approaches to log GW theory (algebraic and symplectic) and then describe a comparison theorem relating them. This is based on joint work with Mohammad Farajzadeh-Tehrani.
