Abstract: 

One of the biggest differences between differential geometry and algebraic geometry is the presence of singularities. In particular, the study of their resolutions constitutes a huge branch in algebraic geometry. In this seminar I will show some useful techniques in resolutions of singularities (especially in dimension 2 & 3). I will try to explain the groups theory aspect of this story in terms of crepant resolutions and Mckay correspondence.
