Résumé

An ordered set (u 1, ..., un ) of positive Cn (a, b)-solutions of the linear differential equation 1.1 will be called fundamental principal system on [a, b) provided that 1.2 and 1.3 A system (u 1, ..., un) satisfying just (1.2) will be called a principal system on [a, b). In any principal system (u 1, ..., un ) the solution u 1 will be called a minimal solution.
