D-branes, T-duality, and index theory
We show that the transformation of D-branes under T-duality on four-torus is represented by Nahm transform of instantons.The argument for this allows us to generalize Nahm transform to the case of orthogonal and symplectic gauge groups as well as to instantons on Z2 orbifold of four-torus.In addition, we identify the …
