“…Cadman and Chen computed the orbifold invariants for rational curves with tangency to a smooth plane cubic [CC08,Theorem 3.5] and observed their agreement with Gathmann's earlier calculation of the relative invariants [Gat03,Section 2,table,p. 409], even when neither invariant is enumerative.…”

“…409], even when neither invariant is enumerative. Thus we arrive at the coincidence observed by Cadman and Chen [CC08], already described in Section 1.1. Our general comparison result, Theorem 1.1, explains this coincidence and generalizes it to rational curves in arbitrary targets.…”
We prove that genus 0 Gromov-Witten invariants of a smooth scheme relative to a smooth divisor coincide with genus 0 orbifold Gromov-Witten invariants of an appropriate root stack construction along the divisor. The proof is given at the level of virtual fundamental classes.

“…In this paper, those large-age markings are studied and translated into markings with negative contact orders. We remark that a very special case of orbifold invariants with large-age markings was studied in [3,Section 5] in details. This paper in fact provides two equivalent definitions of relative Gromov-Witten theory with negative contact.…”
In this paper, we define genus‐zero relative Gromov–Witten invariants with negative contact orders. Using this, we construct relative quantum cohomology rings and Givental formalism. A version of Virasoro constraints also follows from it.
“…Computations in Gromov-Witten theory of stacks beyond orbifold cohomology are not as numerous. C. Cadman [11,12] computed Gromov-Witten invariants of r (P 2 , C) with C a smooth cubic, and derived the number of rational plane curves of degree d with tangency conditions to the cubic C.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
