Query: Wall-crossing, Toric divisor and Seiberg duality   We study the wall-crossing phenomena of BPS D4-D2-D0 states on the conifold
and orbifold C^2/Z_2, from the viewpoint of the quiver quantum mechanics on the
D-branes. The Kahler moduli dependence of the BPS index is translated into the
FI parameter dependence of the Witten index. The wall-crossing phenomena are
related to the Seiberg dualities of the quiver quantum mechanics. All the
differences from the D6-D2-D0 case arise from the additional superpotential and
"anti-quark" induced by the D4-brane. When the D-branes are on the conifold,
the flop transition changes the duality cascade. When the D-branes are on the
orbifold C^2/Z_2, the generating function of the Witten index is always given
by a character of the affine SU(2) algebra. Both are consistent with the
wall-crossing formula for BPS indices.
