Fractional two-branes, toric orbifolds and the quantum McKay correspondence
Bobby Ezhuthachan, Suresh Govindarajan, T. Jayaraman
We systematically study and obtain the large-volume analogues of fractional two-branes on resolutions of orbifolds C^3/Z_n. We study a generalisation of the McKay correspondence pr…
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…
Disc Instantons in Linear Sigma Models
Suresh Govindarajan, T. Jayaraman, Tapobrata Sarkar
We construct a linear sigma model for open-strings ending on special Lagrangian cycles of a Calabi-Yau manifold. We illustrate the construction for the cases considered by Aganagic…
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…
Boundary Fermions, Coherent Sheaves and D-branes on Calabi-Yau manifolds
Suresh Govindarajan, T. Jayaraman
We construct boundary conditions in the gauged linear sigma model for B-type D-branes on Calabi-Yau manifolds that correspond to coherent sheaves given by the cohomology of a monad…
D-branes, Exceptional Sheaves and Quivers on Calabi-Yau manifolds: From Mukai to McKay
Suresh Govindarajan, T. Jayaraman
We present a method based on mutations of helices which leads to the construction (in the large volume limit) of exceptional coherent sheaves associated with the or…
