@article{Tezuka2001RelationsBN, title={Relations between Non-Commutative and Commutative Spacetime}, author={Kenichi Tezuka}, journal={arXiv: High Energy Physics - Theory}, year={2001} }

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($p-2$)-branes, since coordinates of many D-branes are promoted to matrices the worldvolume theory is non…

### A Relation Between Commutative and Noncommutative Descriptions of D-Branes

- Mathematics
- 1999

In string theory D-branes can be expressed as a configuration of infinitely many lower-dimensional D-branes. Using this relation, the worldvolume theory of D-branes can be regarded as the worldvolume…

We extend earlier ideas about the appearance of noncommutative geometry in string theory with a nonzero B-field. We identify a limit in which the entire string dynamics is described by a minimally…

### D-brane Physics and Noncommutative Yang-Mills Theory

- Physics
- 1999

We discuss the physics of a single Dp-brane in the presence of a background electromagnetic field B_{ij}. It has recently been shown \cite{SW} that, in a specific \alpha ' \to 0 limit, the physics of…

### World volume noncommutativity versus target space noncommutativity

- Mathematics
- 1999

It is known that the noncommutativity of D-brane coordinate is responsible for describing the higher-dimensional D-branes in terms of more fundamental ones such as D-particles or D-instantons, while…

### Manifest Supersymmetry in Non-Commutative Geometry

- Physics
- 1999

We consider the open superstring ending on a D-brane in the presence of a constant NS-NS B field, using the Green-Schwarz formalism. Quantizing in the light-cone gauge, we find that the…

### A path integral representation of the map between commutative and noncommutative gauge fields

- Mathematics

The world-volume theory on a D-brane in a constant B-field background can be described by either commutative or noncommutative Yang-Mills theories. These two descriptions correspond to two different…

### Canonical quantization of open string and noncommutative geometry

- Physics

We perform canonical quantization of open strings in the $D$-brane background with a $B$-field. Treating the mixed boundary condition as a primary constraint, we get a set of secondary constraints.…
