Asymptotic behavior of nonoscillatory solutions to $$n$$-th order nonlinear neutral differential equations. (English) Zbl 1157.34057
For the class of $$n$$th order nonlinear neutral differential equations
$(x(t)+p(t)x(t-\tau))^{(n)}+f(t,x(t),x(\rho(t)),x'(t),x'(\sigma(t)))=0$
sufficient conditions for all nonoscillatory solutions to satisfy $$\lim_{t\to\infty}t^{1-n}x(t)=a$$ are presented.
