摘要
综述了近年来无限维动力系统数值分析中的几个主要问题的进展情况,包括大时间收敛性、近似吸引子的存在性、上下半连续性以及近似吸引子的几何结构等.
The advances 0f some essential problems on numerical analysis of infinite dimension al dynamical systems in recent years are commented. These include the large time conver gence, the existence of approximation attractors, the upper semicontinuity and lower semicon tinuity of approximation attractors, and their geometric constructions.
