The present note is an announcement of ''results concerning the parametrization, in the sense of local moduli of the equivalence classes of a system of meromorphic differential equations of the form \(du/dz=Au\) near an irregular singular point (assumed to be \(z=0)\). Here u is an n- component column vector, A is an \(n\times n\) matrix of meromorphic functions''. The equivalence of analytic families of the system given by the above differential equation is studied and it is based in a fundamental way in the theory of formal equivalence over general rings developed by the authors in their monograph entitled ''Deformations of nilpotent matrices over rings and reduction of analytic families of meromorphic differential equations'', to be published in Mem. Am. Math. Soc.
