Abstract:

This paper is concerned with the
nonlinear impulsive neutral delay differential equation with
positive and negative coefficients,

$\left\{ \begin{array}{ll} [x(t)-c(t)x(t-\tau)]'+p(t)f(x(t-\delta))-q(t)f(x(t-\sigma))=0,\quad t\geq t_0,~ t\not= t_k, \\ x(t_k)= b_kx(t_k^-)\\ \disp\qquad \quad\ \ +(1-b_k)\left(\int^{t_k}_{t_k-\delta}p(s+\delta)f(x(s)){\rm d}s- \int^{t_k}_{t_k-\sigma}q(s+\sigma)f(x(s)){\rm d}s\right),\\ \hskip 9.7cm k=1,2,3,\cdots. \end{array} \right.$
Sufficient conditions are obtained for every solution of
the above equation tending to a constant as

$t\to \infty$ .
