D-branes in Generalized Geometry and Dirac-Born-Infeld Action
Tsuguhiko Asakawa, Shuhei Sasa, Satoshi Watamura
The purpose of this paper is to formulate the Dirac-Born-Infeld (DBI) action in a framework of generalized geometry and clarify its symmetry. A D-brane is defined as a Dirac struct…
Angles in Fuzzy Disc and Angular Noncommutative Solitons
Shinpei Kobayashi, Tsuguhiko Asakawa
The fuzzy disc, introduced by the authors of Ref.[1], is a disc-shaped region in a noncommutative plane, and is a fuzzy approximation of a commutative disc. In this paper we show t…
Boundary state analysis on the equivalence of T-duality and Nahm transformation in superstring theory
Tsuguhiko Asakawa, Ursula Carow-Watamura, Yoshiro Teshima +1
We investigated the equivalence of the T-duality for a bound state of D2 and D0-branes with the Nahm transformation of the corresponding gauge theory on a 2-dimensional torus, usin…
