摘要通过更精确的先验估计，利用重合度理论中的连续定理，研究了一类时滞种群模型的周期解，获得了这类模型存在正周期解的充分条件，所得结果推广了有关结论，并使条件有所减弱。 |
| 8. | While the augmentation approach generallyresults in higher state dimension and thus high computational cost , especiallythe systems under investigation involves multiple delays and the delays are large . for continuous - time systems , the delayed problems can in principle be treatedby the infinite - dimensional operator riccati equations which are di ? cult to beunderstood and implemented
然而,当系统有多个时滞且时滞较大时,增广系统将会导致系统维数增加,计算量增大。连续系统的时滞问题通常用到无穷维算子的riccati方程,这种算子方程既难于理解又不便应用。 |
