TITLEQuiver Algebra and Invariant Counting

ABSTRACT In this talk we describe how to solve certain state counting problem in physics/string theory by using quiver techniques and the wallcrossing behavior under the variations of the stability conditions.

We will then discuss the connection with the generalized Donaldson-Thomas invariants.
