Kolloquium Wilhelm Killing: Prof. Dr. William Crawley-Boevey (Universität Bielefeld): My struggle with the Deligne Simpson problem

Mathematik und Informatik

The Deligne Simpson problem (DSP) arises in the classification of linear ODEs in the complex domain, but it is elementary to state: given k conjugacy classes in GL(n,C), determine whether or not there are matrices in these classes with no common invariant subspace and product equal to the identity. Work I did on quiver algebras led to a conjectural answer for the DSP, I proved one direction in 2006 with P. Shaw, and although I announced a proof of the other direction, it never got written up. In this talk I will explain the background to the DSP and discuss recent work with A. Hubery aimed at completing the other direction.
