Orbifold and logarithmic structures provide independent routes to the virtual enumeration of curves with tangency orders for a simple normal crossings pair $(X| D) $. The theories do not …
Multi-scale differentials are constructed in [BCGGM3], from the viewpoint of flat and complex geometry, for the purpose of compactifying moduli spaces of curves together with a …

Given a smooth projective variety X and a smooth divisor D⊂ X, we study relative Gromov– Witten invariants of (X, D) and the corresponding orbifold Gromov–Witten invariants of the r …

We define a new Gromov–Witten theory relative to simple normal crossing divisors as a limit of Gromov–Witten theory of multi-root stacks. Several structural properties are proved …

Let X be a smooth projective variety with a simple normal crossing divisor D:= D 1+ D 2+⋯+ D n, where D i⊂ X are smooth, irreducible and nef. We prove a mirror theorem for multi-root …

We construct a proper moduli space which is a Deligne–Mumford stack parametrising quasimaps relative to a simple normal crossings divisor in any genus using logarithmic …

We study how relative quantum cohomology, defined by Tseng--You and Fan--Wu--You, varies under birational transformations. For toric complete intersections with simple normal …
