Title: Reflexive modules on quotient surface singularities and the McKay
correspondence.
Abstract: These two lectures will give an overview of MacKay
correspondence which relates (irreducible representations) of finite
subgroups G of SL(2,C), and (indecomposable) reflexive modules over
C[|X,Y|]^G. The first lecture will be of an introductory nature, talking
about finite subgroups of GL(n,C) in general, and singularity theory.
