The N-eigenvalue Problem and Two Applications

Abstract

We consider the classification problem for compact Lie groups GU(n)G\subset U(n) which are generated by a single conjugacy class with a fixed number NN of distinct eigenvalues. We give an explicit classification when N=3, and apply this to extract information about Galois representations and braid group representations.
