摘要
The objective of this paper is to offer sufficient conditions for all nonoscillatory solutions of the third-order functional differential equation [a(t) [x'(t)](gamma) + p(t)x(beta)(tau(t)) = 0 tend to zero. Our results are based on the new comparison theorems. Studied equation is in a canonical form, i.e., integral(infinity) a(-1/gamma)(s)ds = infinity, and we consider both delay and advanced case of it. The results obtained essentially improve and complement earlier ones.
