Dynamics of an almost periodic competitor-competitor-mutualist Lotka-Volterra systems with time delays

By using Mawhin's continuation theorem of coincidence degree theory and constructing a suitable Lyapunov functional, a set of easily verifiable conditions are obtained for the existence and global asymptotical stability of a unique positive almost periodic solution of competitor-competitor-mutualist Lotka-Volterra systems with time delays. An example and simulations are employed to illustrate the main results of this paper.
