Periodic solutions in higher-dimensional Lotka-Volterra neutral competition systems with state-dependent delays. (English) Zbl 1134.34046

The present paper is concerned with the existence of periodic solutions for a class of neutral Lotka-Volterra system with state-dependent delays. The approach is to use the continuation theorem of the coincidence degree theory due to Mawhin. More general higher-dimensional systems were discussed similarly.
