The Ruled Vertex and D-E Degenerations

Abstract

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 ruled vertex formalism for degenerate torus actions.
