摘要：In this paper, we study a $n$-species Lotka-Volterra competition model with weak delay kernel and time dependent delay. By using the method of coincidence degree, a set of sufficient conditions are obtained for the existence of at least one strictly positive periodic solutions. Some known results are improved.
