摘要

本文讨论了线性微分方程非自治系统的非一致指数二分性。由于任何线性微分系统在运动上都与三角系统相似，因此有必要考虑三角系统的非均匀指数二分性之间的关系。在不失一般性的前提下，考虑了块状上三角形系统，给出了无界系统半线上三角形系统非一致指数二分的判据。

Nonuniform exponential dichotomy for block triangular systems on the half line

In this paper, we discuss the nonuniform exponential dichotomy properties of nonautonomous systems of linear differential equations. Since any linear differential systems are kinematically similar to a triangular system, considering the relation between the nonuniform exponential dichotomy properties of the triangular system is necessary. Without loss of generality, we consider block upper triangular systems and give the criteria for the nonuniform exponential dichotomy of triangular systems on the half line for unbounded systems.
