Title: BPS State Wallcrossing and ADHM Sheaf Theory (Part I)
Date (JST): Mon, Feb 06, 2012, 14:00 - 15:00
Place: Seminar Room A
Abstract: Part I:
In the first part of the talk I will review the physics of D-brane BPS state counting, stability condition and wallcrossing. The physics derivation of the wallcrossing formulas will also be discussed. After that I will specialize to the geometry where quiver description is available and discuss theta stability condition, stable representations and mutations.
