Title: Weakly-Exceptional Quotient Singularities.
Abstract: The classification of A-D-E singularities on surfaces and their relation to Platonic solids and regular polygons is a very well-known classical result. I will discuss one of the possible generalizations of this idea into higher dimensions and some recent results on the classification of such singularities. http://www.maths.ed.ac.uk/cheltsov/seminar/
