On the polynomiality of orbifold Gromov--Witten theory of root stacks (2001.00244v2)

Abstract: In \cite{TY18}, higher genus Gromov--Witten invariants of the stack of $r$-th roots of a smooth projective variety $X$ along a smooth divisor $D$ are shown to be polynomials in $r$. In this paper we study the degrees and coefficients of these polynomials.
