MAXIMAL AND MINIMAL SOLUTIONS OF TERMINAL VALUE PROBLEMS FORDIFFERENTIAL EQUATIONS IN BANACH SPACES
Banach空间一阶微分方程终值问题的解

In this paper, by the use of new comparison results and the order methods innonlinear analysis, we study the existence of maximal and minimal solutions of terminal valueproblems for differential equations in Banach spaces. Some known results are improved andgeneralized.
