On the normal form and the reducibility of linear completely integrable systems with quasiperiodic coefficients. (English)
Authors: Hincu V.
Abstract
The reducibility problem for the linear differential systems with multidimentional time and quasiperiodic coefficients is considered. Under the assumption of some condition of incommensurability between the coefficient's mean values and the frequency matrix, the reducibility of analytical systems with triangular form to systems with constant coefficients is proved.Universitatea de stat din Moldova
