摘要:
For the delay differential equations (x) double under dot (t) + a(t) (x) over dot(g(t)) + b(t)x(h(t)) = 0, g(t) <= t, h(t) <= t, and (x) double under dot (t) + a(t) (x) over dot(g(t)) + b(t)x(h(t)) = a(1)(t)(x) over dot(g(t)) +b(1)(t)(x) over dot(h(t)) = 0 explicit exponential stability conditions are obtained.
