We study D-branes on three-dimensional orbifolds C/Î“ where Î“ are finite subgroups of SU(3). The quiver diagram of Zn Ã— Zn âˆˆ SU(3) can be expressed in three-dimensional form. According to theâ€¦ (More)

We study brane configurations corresponding to D-branes on complex threedimensional orbifolds C/Î“ with Î“ = âˆ†(3n) and âˆ†(6n), nonabelian finite subgroups of SU(3). We first construct a braneâ€¦ (More)

We study D-branes on a three complex dimensional nonabelian orbifold C/Î“ with Î“ a finite subgroup of SU(3). We present general formulae necessary to obtain quiver diagrams which represent the gaugeâ€¦ (More)

We consider D-branes on an orbifold C/Zn and investigate the moduli space of the D-brane world-volume gauge theory by using toric geometry and gauged linear sigma models. For n = 11, we find thatâ€¦ (More)

We study phase structure of the moduli space of a D0-brane on the orbifold C3/Z2 Ã— Z2 based on stability of quiver representations. It is known from an analysis using toric geometry that this modelâ€¦ (More)

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 comparedâ€¦ (More)

We study N = 2 supersymmetric SU(2)/U(1) and SL(2, R)/U(1) gauged WessZumino-Witten models. It is shown that the vector gauged model is transformed to the axial gauged model by a mirrorâ€¦ (More)
