TITLE	ADHM sheaf theory and related moduli problems
ABSTRACT	In this talk I will introduce ADHM sheaf theory of local curves, which is an alternative construction for the local stable pair theory of Pandharipande and Thomas. The wallcrossing formula can be derived and used to compute higher rank DT invariants. The theory also gives rise to applications to the computation of the cohomology of Hitchin moduli space.
