    On trouve des conditions sous lesquelles les classes d'unicité de la solution du problème de Cauchy pour les systèmes d'équations \(D_ tu(x,t)=P(D_ x)u(x,t),\) respectivement \[ D_ tu(x,t)=P(D_ x)u(x,t)+Q[u]+R[u],\quad (x,t)\in {\mathbb{R}}^ m\times [0,T], \] coincident. On suppose \[ Q[u]=\sum_{\alpha \in A}Q_{\alpha}(D_ x)u(x_{\alpha},t),\quad R[u]=\sum_{\beta \in B}R_{\beta}(D_ x)u(x_{\beta},t_{\beta}), \] où A et B sont des ensembles finis, \(x_{\alpha}\in {\mathbb{R}}^ m\), \((x_{\beta},t_{\beta})\in {\mathbb{R}}^ m\times [0,T],\quad u(x,t)\in {\mathbb{C}}^ n,\) P, \(Q_{\alpha}\) et \(R_{\beta}\) sont des matrices \(n\times n\), aux éléments polynômes sur \({\mathbb{C}}^ m\).
