D-brane effective action and tachyon condensation in topological minimal models
Manfred Herbst, Calin-Iuliu Lazaroiu, Wolfgang Lerche
We study D-brane moduli spaces and tachyon condensation in B-type topological minimal models and their massive deformations. We show that any B-type brane is isomorphic with a dire…
Localization and traces in open-closed topological Landau-Ginzburg models
Manfred Herbst, C. I. Lazaroiu
We reconsider the issue of localization in open-closed B-twisted Landau-Ginzburg models with arbitrary Calabi-Yau target. Through careful analsysis of zero-mode reduction, we show…
Superpotentials, A-infinity Relations and WDVV Equations for Open Topological Strings
Manfred Herbst, C. I. Lazaroiu, Wolfgang Lerche
We give a systematic derivation of the consistency conditions which constrain open-closed disk amplitudes of topological strings. They include the A-infinity relations (which gener…
