• Resumen

  • In this paper we show that, previous results given by Coppel concerning the existence of projection matrix P, and a change of variable x = S(t)y reducing system x = A(t)x, where A(t) is a continuous matrix function, to the form y= A(t)y, with the property P A(t) = A(t)P, can be extended to the case when A(t) is a locally integrable function.
