Massive 3d Abelian gauge theories and electric-magnetic duality
Ansar Fayyazuddin
We study a model of massive photons with a parity invariant and non-local mass term. We identify a discrete symmetry of the classical equations of motion and show that this symmetr…
Non-local symmetries for Yang-Mills theories and their massive counterparts in two and three dimensions
Abhishek Agarwal, Ansar Fayyazuddin
We identify a non-local symmetry for Yang-Mills theories in 1+1 and 2+1 spacetime dimensions. The symmetry mixes a vector current with the gauge field. The current involved in the…
Calabi-Yau 3-folds from 2-folds
Ansar Fayyazuddin
We consider type IIA string theory on a Calabi-Yau 2-fold with D6-branes wrapping 2-cycles in the 2-fold. We find a complete set of conditions on the supergravity solution for any…
holonomy metrics and wrapped D6-branes
Ansar Fayyazuddin, Tasneem Zehra Husain
We determine torsion class constraints for the supergravity background produced by D6-branes wrapping special Lagrangian cycles in a Calabi-Yau 3-fold. We employ a recently introdu…
Ten and eleven dimensional perspectives on N=2 black holes
Ansar Fayyazuddin
We give an 11 and 10 dimensional supergravity description of M5-branes wrapping 4-cylces in a Calabi-Yau manifold and carrying momentum along a transverse S. These wrapped bran…
Calibrations, Torsion Classes and Wrapped M-Branes
Ansar Fayyazuddin, Tasneem Zehra Husain
The present work has two goals. The first is to complete the classification of geometries in terms of torsion classes of M-branes wrapping cycles of a Calabi-Yau. The second goal i…
