چکیده

We calculate the metric on the D-brane vacuum moduli space for backgrounds of the form C 3 /Γ for cyclic groups Γ. In the simplest procedure — starting with a flat " seed " metric on the covering space — we find that the resulting D-brane metric is not Ricci-flat. We argue that this is likely to be true of the true 0-brane metric at weak string coupling.

Brane Cube Realization of Three-dimensional Nonabelian Orbifolds

We study D-branes on three-dimensional orbifolds C/Γ where Γ are finite subgroups of SU(3). The quiver diagram of Zn × Zn ∈ SU(3) can be expressed in three-dimensional form. According to the correspondence between quiver diagrams and brane configurations, we construct a brane configuration for C/Zn×Zn which has essentially three-dimensional structrue. Brane configurations for nonabelian orbifol...

Brane Configurations for Three-dimensional Nonabelian Orbifolds

We study brane configurations corresponding to D-branes on complex threedimensional orbifolds C/Γ with Γ = ∆(3n) and ∆(6n), nonabelian finite subgroups of SU(3). The brane configurations consist of D3-branes on webs of (p, q) 5-branes of type IIB string theory. The structure of irreducible representations of the groups ∆(3n) and ∆(6n) can be explained from the brane configurations. We also disc...

Orientifolds of Non-Supersymmetric, Asymmetric Orbifolds

We consider certain four dimensional supersymmetric and non-supersymmetric asymmetric orbifolds with vanishing cosmological constant up to two loops and gauge the world sheet parity transformation. These models contain bound states of Dp and D(p-4) branes or Dp and D(p-4) branes, respectively. Moreover, it is shown that different degrees of supersymmetry can be realized in the bulk and on the b...

Null orbifolds in AdS, Time Dependence and Holography

We study M/D-branes in a null-brane background. By taking a near horizon limit, one is left with cosmological models in the corresponding Poincaré patches. To deal with their usual horizons, we either extend these models to global AdS or remain in the Poincaré patch and apply a T-duality transformation whenever the effective radius of the compact dimension associated with the null-brane probes ...

D-geometric structure of orbifolds

We study D-branes on abelian orbifolds C/ZN for d = 2, 3. The toric data describing the D-brane vacuum moduli space, which represents the geometry probed by D-branes, has certain redundancy compared with the classical geometric description of the orbifolds. We show that the redundancy has a simple combinatorial structure and find analytic expressions for degrees of the redundancy. For d = 2 the...
