Matrix model and noncommutative Chern-Simons theory
J. Kluson
In this short paper we would like to present a simple topological matrix model which has close relation with the noncommutative Chern-Simons theory.
D-Branes from N non-BPS D0-Branes
J. Kluson
In this paper we would like to show that from N non-BPS D0-branes in type IIB theory we can obtain all BPS and non-BPS D-branes through the tachyon condensation in the large N limi…
Non-commutative Soliton Scattering
Ulf Lindstrom, Martin Rocek, Rikard von Unge
We study solitons in three dimensional non-commutative scalar field theory at infinite non-commutativity parameter. We find the metric on the relative moduli space of all solitons…
S-Duality, Noncritical Open String and Noncommutative Gauge Theory
Soo-Jong Rey, Rikard von Unge
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 theo…
Proposal for non-BPS D-brane action
J. Kluson
In this short note we would like to propose a form for the action of a non-BPS D-brane, which will be manifestly supersymmetric invariant and T-duality covariant. We also explicitl…
Hyperkähler Quotients, Mirror Symmetry, and F-theory
I. Y. Park, R. von Unge
Using the graphical method developed in hep-th/9908082, we obtain the full curve corresponding to the hyperkähler quotient from the extended E_7 Dynkin diagram. As in the E_6 case…
