Abstract

We prove a higher genus version of the genus local-relative correspondence of van Garrel-Graber-Ruddat: for a pair with a smooth projective variety and a nef smooth divisor, maximal contact Gromov-Witten theory of with -insertion is related to Gromov-Witten theory of the total space of and local Gromov-Witten theory of . Specializing to for a del Pezzo surface or a rational elliptic surface and a smooth anticanonical divisor, we show that maximal contact Gromov-Witten theory of is determined by the Gromov-Witten theory of the Calabi-Yau 3-fold and the stationary Gromov-Witten theory of the elliptic curve . Specializing further to , we prove that higher genus generating series of maximal contact Gromov-Witten invariants of are quasimodular and satisfy a holomorphic anomaly equation. The proof combines the quasimodularity results and the holomorphic anomaly equations previously known for local and the elliptic curve. Furthermore, using the connection between maximal contact Gromov-Witten invariants of and Betti numbers of moduli spaces of semistable one-dimensional sheaves on , we obtain a proof of the quasimodularity and holomorphic anomaly equation predicted in the physics literature for the refined topological string free energy of local in the Nekrasov-Shatashvili limit.
