Periodic solutions in higher-dimensional Lotka–Volterra neutral competition systems with state-dependent delays

摘要

Positive periodic solutions for two-dimensional neutral Lotka–Volterra system with state-dependent delays are considered by the theory of coincidence degree and some new techniques of computation. Applying this method for higher-dimensional system, we can also get more general conclusions and give many easy and verifiable conditions for some special cases of system by restricting its coefficients.
