Abstract:

In this paper authors obtain sufficient conditions under which every solution of theneutral differential equations with several delay arguments and positive-negative coefficients
[x(t)-Σ k=1lCk(t)x(t-rk)]+Σi=1mPi(t)x(t-τi)-Σj=1nQj(t)x(t-σj)=0,tt0,tends to a constant as t→∞.This paper extends the result of[5] to the case of several delayarguments.

Key words: Neutral differential equation, several delay arguments, asymptotic behavior
