Motivic DT-invariants of (-2)-curves

Abstract: In the first part of my talk I will gently introduce (0,-2)-curves and sketch how they show up in resolutions of singular 3-folds. After that, an alternative non-commutative resolution using quivers with potential is given. Finally, I will briefly introduce Donaldson-Thomas invariants and state the answer in our situation which is the main result of a joint work with Ben Davison.
