D-branes on Calabi-Yau Manifolds and Superpotentials
Michael R. Douglas, Suresh Govindarajan, T. Jayaraman +1
We show how to compute terms in an expansion of the world-volume superpotential for fairly general D-branes on the quintic Calabi-Yau using linear sigma model techniques, and show…

D-branes and Vector Bundles on Calabi-Yau Manifolds: a view from the Helix
Suresh Govindarajan, T. Jayaraman
We review some recent results on D-branes on Calabi-Yau (CY) manifolds. We show the existence of structures (helices and quivers) which enable one to make statements about large fa…

On the Landau-Ginzburg description of Boundary CFTs and special Lagrangian submanifolds
Suresh Govindarajan, T. Jayaraman
We consider Landau-Ginzburg (LG) models with boundary conditions preserving A-type N=2 supersymmetry. We show the equivalence of a linear class of boundary conditions in the LG mod…
