Kolloquium Wilhelm Killing: Prof. Dr. William Crawley-Boevey (Universität Bielefeld): My struggle with the Deligne Simpson problem
Thursday, 28.06.2018 16:30 im Raum M5
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.
