| Abstract | Let X->Y be a birational contraction of relative dimension no bigger than one. It is an interesting question whether the infinitesimal deformation of the exceptional curve determine the singularities of Y. When X->Y is a three dimensional flopping contraction, we show that the answer to the above question is yes. This gives a positive answer to a conjecture of Donovan and Wemyss. This talk is based on the a joint work with Yukinobu Toda 1601.04881 and the work 1610.05467. |
