Non-commutative branes in D-brane backgrounds
نویسنده
چکیده
We study Myers world-volume effective action of coincident D-branes. We investigate a system of N0 D0-branes in the near horizon geometry of Dp-branes with p = 2 or p = 4. The choice of coordinates can make the action simplified and tractable. For p = 4, we show that a certain point-like D0-brane configuration solving equations of motion of the action can expand to form a fuzzy two-sphere without changing quantum numbers. We compare non-commutative D0-brane configurations with dual spherical D(6 − p)-brane systems. We also discuss the relation between these configurations and giant gravitons in 11-dimensions. †E-mail address: asano@hep-th.phys.s.u-tokyo.ac.jp

A Construction of Commutative D-branes from Lower Dimensional Non-BPS D-branes
We construct an exact soliton, which represents a BPS Dp-brane, in a boundary string field theory action of infinitely many non-BPS D(p − 1)-branes. Furthermore, we show that this soliton can be regarded as an exact soliton in the full string field theory. The world-volume theory of the BPS Dp-brane constructed in this way becomes usual gauge theory on commutative R, instead of non-commutative ...
متن کاملBrane Dynamics in Cft Backgrounds *
In this note we discuss bound states of unor meta-stable brane configurations in various non-trivial (curved) backgrounds. We begin by reviewing some known results concerning brane dynamics on group manifolds. These are then employed to study condensation in cosets of the WZWmodel. While the basic ideas are more general, our presentation focuses on parafermion theories and, closely related, N =...
متن کاملNon-commutative Branes from M-theory
The analysis of the worldvolume effective actions of the M-theory Kaluza-Klein monopole and 9-brane suggests that it should be possible to describe non-abelian configurations of M2-branes or M5-branes if the M2-branes are transverse to the eleventh direction and the M5-branes are wrapped on it. This is determined by the fact that the Kaluza-Klein monopole and the M9-brane are constrained to mov...
متن کاملRelations between Non-Commutative and Commutative Spacetime1
Spacetime non-commutativity appears in string theory. In this paper, the non-commutativity in string theory is reviewed. At first we review that a Dp-brane is equivalent to a configuration of infinitely many D(p− 2)-branes. If we consider the worldvolume as that of the Dp-brane, coordinates of the Dp-brane is commutative. On the other hand if we deal with the worldvolume as that of the D(p− 2)-...
متن کاملDynamics of D-branes in curved backgrounds
In recent years, the study of branes has led to many new insights into string and M-theory. Much of this study was done in the large-volume regime where geometric techniques provide reliable information. The extrapolation into the stringy regime usually requires new methods from boundary conformal field theory. Branes on group manifolds give us a good handle on this issue. Although they describ...
