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.
