一类中立型变时滞微分系统的大范围吸引性

Global attractability of solutions of a certain neutral differential equation with variable delays

利用构造Liapunov泛函的方法 ,给出了中立型变时滞微分方程 ddt[x(t) +ax(t τ(t) ) ]=bx(t) +cx(t τ1(t) )零解大范围吸引的一个简洁。

By use of liapunov function method on the following neutral differential equation with variable delays dd t[x(t)+ax(t τ(t))]=bx(t)+cx(t τ 1(t))this paper made a simple criterion to judge its solution in global attractability.
