Research output: Contribution to journalArticlepeer-review

We compute all genus topological amplitudes on configurations of ruled surfaces obtained by resolving lines of D-E singularities in compact Calabi-Yau threefolds. We find that our results are in agreement with genus zero mirror symmetry calculations, which is further evidence for the validity of the ruled vertex formalism for degenerate torus actions.
