چکیده

We study 0-branes in type IIA on T 2 with a background B-field turned on. This enables us to find the matrix model for M-theory on T 2 with a background 3-form potential along the torus and the lightlike circle. The theory is a non-local 2+1 dim SYM theory on a dual T 2 exactly as proposed by Connes,Douglas and Hull. We calculate the radii and the gauge coupling for the SYM on the dual T 2 for all choices of longitudinal momentum and membrane wrapping number on the T .

S - wave absorption of scalars by noncommutative D 3 - branes

On the supergravity side, we study the propagation of the RR scalar and the dilaton in the D3-branes with NS B-field. To obtain the noncommutative effect, we consider the case of B → ∞(θ → π/2). This corresponds to the black D-string background. In this background, the RR scalar induces an instability of the near-horizon geometry. However, it turns out that the RR scalar is nonpropagating, whil...

Noncommutative Geometry from D0-branes in a Background B-field

We study D0-branes in type IIA on T 2 with a background B-field turned on. We calculate explicitly how the background B-field modifies the D0-brane action. The effect of the Bfield is to replace ordinary multiplication with a noncommutative product. This enables us to find the matrix model for M-theory on T 2 with a background 3-form potential along the torus and the lightlike circle. This matr...

Greybody factor for D 3 - branes in B field

We calculate the effect of noncommutative spacetime on the greybody factor on the supergravity side. For this purpose we introduce a system of D3-branes with a constant NS B-field along their world volume directions (x 2 , x 3). Considering the propagation of minimally coupled scalar with non-zero momentum along(x 2 , x 3), we derive an exact form of the greybody factor in B field. It turns out...

D0-branes in a H-field Background and Noncommutative Geometry

It is known that if we compactify D0-branes on a torus with constant B-field, the resulting theory becomes SYM theory on a noncommutative dual torus. We discuss the extension to the case of a H-field background. In the case of a constant H-field on a three-torus, we derive the constraints to realize this compactification by considering the correspondence to string theory. We carry out this work...
