Abstract: A classical theorem by Poincaré gives conditions that a nonlinear ordinary differential equation $\displaystyle dx/dt = A(x),$ with $A(0) = 0$ in n variables $x = ({x_1}, \ldots ,{x_n})$ can be reduced to a linear form $\displaystyle \frac{{dx'}}{{dt}} = \frac{{\partial A}}{{\partial x}}(0)x'$ by a change of variables $x' = f(x)$. A generalization is given for a finite set of such differential equations, which form a semisimple Lie algebra.
