Open Topological String Amplitudes on Calabi-Yau Threefolds by Extended Holomorphic Anomaly Equation (2207.11501v3)
Published 23 Jul 2022 in hep-th
Abstract: In this paper, we study the open topological string amplitudes on Calabi-Yau threefolds by the extended holomorphic anomaly equation. The disk two-point function determined by the domainwall tension, together with the Yukawa couplings, solves the amplitudes with high genus and boundaries recursively. The BPS invariants encoded in the amplitudes are extracted by mirror symmetry.
