考虑分段常变元时滞微分方程x′(t)+a(t)x(t)+b(t)x([t-l])=0的振动性,其中a(t)和b(t)是在[-k,∞)上的连续函数,b(t)≥0,k是正整数[·]表示最大整函数,得到了一些新的振动条件.

Consider the delay differential equation with piecewise constant argument x'(t) + a(t)x(t) + b(t)x([t-l]) = 0, where a(t) and b(t) are continuous functions on [ - k, ∞), b(t) ≥0, k is a positive integer and [&middot] denotes the greatest integer function, some...
