Oscillation for equations with positive and negative coefficients and distributed delay II: Applications

We apply the results of our previous paper "Oscillation of equations with positive and negative coefficients and distributed delay I: General results" to the study of oscillation properties of equations with several delays and positive and negative coefficients $$ dot{x}(t) + sum_{k=1}^n a_k(t) x(h_k(t)) - sum_{l=1}^m b_l(t) x(g_l(t)) = 0, quad a_k(t) geq 0, b_l(t) geq 0, $$ integrodifferential equations with oscillating kernels and mixed equations combining two above equations. Comparison theorems, explicit non-oscillation and oscillation results are presented.
