Orbifold Resolution by D-Branes
We study topological properties of the D-brane resolution of three-dimensional orbifold singularities, C/Γ, for finite abelian groups Γ. The D-brane vacuum moduli space is shown to fill out the background spacetime with Fayet–Iliopoulos parameters controlling the size of the blow-ups. This D-brane vacuum moduli space can be classically described by a gauged linear sigma model, which is shown to...
متن کاملBranes at Angles and Resolution of Orbifold Singularities
We show that the description of D-branes near an orbifold singularity exactly coincides with that of two branes at angles. We use this observation to study string theory on orbifolds, and resolve these singularities. In addition, we consider the compact manifolds with orbifold type singularities and study branes wrapped on these manifolds through the “branes at angles” picture. In this way we p...
متن کاملAzumaya Structure on D-branes and Resolution of Ade Orbifold Singularities Revisited
In this continuation of [L-Y1] and [L-L-S-Y], we explain how the Azumaya structure on D-branes together with a netted categorical quotient construction produces the same resolution of ADE orbifold singularities as that arises as the vacuum manifold/variety of the supersymmetric quantum field theory on the D-brane probe world-volume, given by Douglas and Moore [D-M] under the string-theory conte...
متن کاملNon-BPS D-branes on a Calabi-Yau Orbifold
A system containing a pair of non-BPS D-strings of type IIA string theory on an orbifold, representing a single D2-brane wrapped on a nonsupersymmetric 2-cycle of a Calabi-Yau 3-fold with (h(1,1), h(1,2)) = (11,11), is analyzed. In certain region of the moduli space the configuration is stable. We show that beyond the region of stability the system can decay into a pair of non-BPS D3-branes. At...
متن کاملOrbifold and Five-branes
We study M(atrix) theory description of M theory compactified on T5/Z2 orbifold. In the large volume limit we show that M theory dynamics is described by N = 8 supersymmetric USp(2N) M(atrix) quantum mechanics. Via zero-brane parton scattering, we show that each orbifold fixed point carries anomalous G-flux ∮ [G/2π] = −1/2. To cancel the anomalous Gflux , we introduce twisted sector consisting ...
