   Abstract:
   This article addresses the problem of computing the Galois group of a product of two completely reducible linear operators with rational function coefficients. It shows how to reduce this problem to the case of a single completely reducible linear operator, which is addressed in a separate article by Compoint and Singer. A decision procedure and several examples are provided.
