Topological DBI actions and nonlinear instantons
A. Imaanpur
We consider Euclidean D4 and D6-branes filling the whole and space, respectively. In both cases, with a constant background B-field turned on for D4-branes,…
On supermembrane actions on Calabi-Yau 3-folds
A. Imaanpur
In this note we examine the supermembrane action on Calabi-Yau 3-folds. We write down the Dirac-Born-Infeld part of the action, and show that it is invariant under the rigid spacet…
A 3d topological sigma model and D-branes
A. Imaanpur
A 3d topological sigma model describing maps from a 3-manifold Y to a Calabi-Yau 3-fold M is introduced. As the model is topological, we can choose an arbitrary metric on M. Upon s…
N = 4 SYM on Σ\times S^2 and its Topological Reduction
A. Imaanpur
We consider the twisted N = 4 SYM on Σ\times S^2. In the limit that S^2 shrinks to zero size the four dimensional theory reduces to a two dimensional SYM theory. We compute the cor…
