Abstract: Commutative nets are a subclass of colored nets whose color functions belong to a ring of commutative diagonalizable endomorphisms. Although their ability to describe models is smaller than that of colored nets, they can handle a broad range of concurrent systems. Commutative nets include net subclasses such as regular homogeneous nets and ordered nets. Mathematical properties of the color functions of commutative nets allow a symbolic computation of a family of generators of flows. The method proposed decreases the number of non-null elements in a given color function matrix, without adding new columns. By iteration, the entire matrix is annulled.
Keywords: linear invariant (in) commutative high-level net; coloured net; diagonalizable endomorphisms; regular homogeneous net; ordered net; symbolic computation (of) flow generators.
