Positive periodic solutions of a neutral functional differential equation with multiple delays

This paper deals with the existence of positive $ømega$-periodic solutions for the neutral functional differential equation with multiple delays (u(t)-cu(t-\delta))'+a(t) u(t)=f(t, u(t-\tau_1), \cdots, u(t-\tau_n)). The essential inequality conditions on the existence of positive periodic...
