11. Finding rational simple eigenvalues of a noncommutative rational


    1. Add remark

      Problem 11.1.

      [Jurij Volčič] Suppose r is a noncommutative rational function. Can we find \Xi, a tuple of matrices over the field of univariate rational functions, such that r(\Xi) is a matrix of rational functions with a simple rational eigenvalue?
        1. Remark. This is related to the centralizer problem for the free skew field.
