The non-commutative geometry of a large auxiliary B-field simplifies the construction of D-
branes as solitons in open string field theory. Similarly, fundamental strings are constructed …

We study the non-critical space-time non-commutative open string (NCOS) theory using a
dual supergravity description in terms of a certain near-horizon limit of the F1-Dp bound …

We study the issue of gauge-invariant observables in d= 4, N= 4 noncommutative gauge
theory and UV–IR relation therein. We show that open Wilson lines form a complete set of …

We examine several aspects of S-duality of four-dimensional noncommutative gauge theory.
By making duality transformation explicit, we find that S-dual of noncommutative gauge …

Noncommutative gauge theories can be constructed from ordinary U (∞) gauge theories in
lower dimensions. Using this construction we identify the operators on noncommutative D …

Following the conjectured duality between near-horizon NS5-branes and little string theory,
the string-corrected thermodynamics of near-horizon NS5-branes is studied and found to …

We investigate the consequences of generalizing certain well established properties of the
open string metric to the conjectured open membrane and open Dp-brane metrics. By …

We study properties of (D (p-2), Dp) nonthreshold bound states (2≤ p≤ 6) in the dual
gravity description. These bound states can be viewed as Dp-branes with a nonzero NS B …

We study T 2 compactification of massive type-IIA supergravity in presence of possible
Ramond-Ramond (RR) background fluxes. The resulting theory in D= 8 is shown to possess …

We show that combining the spatial noncommutative SYM limit and Lorentz transformation,
one can obtain a well-behaved light-like noncommutative SYM limit. The light-like …
