A note on perturbative aspects of Leigh-Strassler deformed N=4 SYM theory
Kallingalthodi Madhu, Suresh Govindarajan
We carry out a perturbative study of the Leigh-Strassler deformed N=4 SYM theory in order to verify that the trihedral Delta(27) symmetry holds in the quantum theory. We show that…
Symplectic potentials and resolved Ricci-flat ACG metrics
Aswin K. Balasubramanian, Suresh Govindarajan, Chethan N. Gowdigere
We pursue the symplectic description of toric Kahler manifolds. There exists a general local classification of metrics on toric Kahler manifolds equipped with Hamiltonian two-forms…
A quantum McKay correspondence for fractional 2p-branes on LG orbifolds
Bobby Ezhuthachan, Suresh Govindarajan, T. Jayaraman
We study fractional 2p-branes and their intersection numbers in non-compact orbifolds as well the continuation of these objects in Kahler moduli space to coherent sheaves in the co…
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…
