Noncommutative Dipole Field Theories
K. Dasgupta, M. M. Sheikh-Jabbari
Assigning an intrinsic constant dipole moment to any field, we present a new kind of associative star product, the dipole star product, which was first introduced in [hep-th/000803…
Geometric Transition versus Cascading Solution
Keshav Dasgupta, Kyungho Oh, Jaemo Park +1
We study Vafa's geometric transition and Klebanov - Strassler solution from various points of view in M-theory. In terms of brane configurations, we show the detailed equivalences…
Geometric Transition, Large N Dualities and MQCD Dynamics
Keshav Dasgupta, Kyungho Oh, Radu Tatar
We study Vafa's geometric transition from a brane setup in M-theory. In this transition D5 branes wrapped on P^1 cycles of a resolved conifold disappear and are replaced by fluxes…
Open/Closed String Dualities and Seiberg Duality from Geometric Transitions in M-theory
Keshav Dasgupta, Kyungho Oh, Radu Tatar
We propose a general method to study open/closed string dualities from transitions in M theory which is valid for a large class of geometrical configurations. By T-duality we can t…
Nonlocal Field Theories and their Gravity Duals
Aaron Bergman, Keshav Dasgupta, Ori J. Ganor +2
The gravity duals of nonlocal field theories in the large N limit exhibit a novel behavior near the boundary. To explore this, we present and study the duals of dipole theories - a…
