Wall-crossing of D4-branes using flow trees
The moduli dependence of D4-branes on a Calabi-Yau manifold is studied using attractor flow trees, in the large volume limit of the Kähler cone.One of the moduli-dependent existence criteria of flow trees is the positivity of the flow parameters along its edges.It is shown that the sign of the flow …
