String Theory, Matrix Model, and Noncommutative Geometry
Compacti cation of Matrix Model on a Noncommutative torus is obtained from strings ending on D-branes with background B eld. The BPS spectrum of the system and a novel SL(2; Z) symmetry are discussed. Noncommutativity of space-time coordinates emerged in string theory recently in the context of coincident Dbranes [1]; in fact the embedding coordinates of D-branes turned out to be noncommutative...
متن کاملNoncommutative Geometry from String Theory: Annulus Corrections
We develop a method in which it is possible to calculate one loop corrections to the noncommutativity parameter found for open strings in a background Fμν field. We first reproduce the well known disk results for θ μν . We then consider the case of charged and neutral open strings on the brane, and show in both cases that the result is the same as in the disk case, apart from a multiplicative f...
متن کاملNoncommutative Geometry and String Duality
A review of the applications of noncommutative geometry to a systematic formulation of duality symmetries in string theory is presented. The spectral triples associated with a lattice vertex operator algebra and the corresponding Dirac-Ramond operators are constructed and shown to naturally incorporate target space and discrete worldsheet dualities as isometries of the noncommutative space. The...
متن کاملNoncommutative Geometry and Spacetime Gauge Symmetries of String Theory
We illustrate the various ways in which the algebraic framework of noncommutative geometry naturally captures the short-distance spacetime properties of string theory. We describe the noncommutative spacetime constructed from a vertex operator algebra and show that its algebraic properties bear a striking resemblence to some structures appearing in M Theory, such as the noncommutative torus. We...
متن کاملLarge Extra Dimensions and Noncommutative Geometry in String Theory
The consequences of noncommutativity of space coordinates of string theory in the proposed large extra dimension solution to the hierarchy problem are explored; in particular the large dimension stabilization and the graviton reabsorption in the brane are considered. [email protected]
