Abstract.
In this paper we present a new method for the formal reduction of linear differential systems. We generalize classical results and concepts and obtain new characterizations of existing notions. Our main result is a generalization of the classical Splitting Lemma. This leads to an algorithm for computing formal invariants and solutions in a more efficient way.
