Abstract

Given a smooth projective variety XX with a smooth nef divisor DD and a positive integer rr, we construct an II-function, an explicit slice of Givental's Lagrangian cone, for Gromov--Witten theory of the root stack XD,rX_{D,r}. As an application, we also obtain an II-function for relative Gromov--Witten theory following the relation between relative and orbifold Gromov--Witten invariants.
