Oscillatory and asymptotic behaviour of a neutral differential equation with oscillating coefficients
In this paper, we obtain sufficient conditions so that every solution of $$ \big(y(t)- \sum_{i=1}^n p_i(t) y(\delta_i(t))\big)'+\sum_{i=1}^m q_i(t) y(\sigma_i(t)) = f(t) $$ oscillates or tends to zero as $t \to \infty$. Here the coefficients $p_i(t), q_i(t)$ and the forcing term $f(t)$ are allo...
