Periodic solution for a delay multispecies Logarithmic population model with feedback control

In this paper, a delay multispecies Logarithmic population model with feedback control is studied. By using the contraction mapping principle as well as a new transformation, some new results on the existence and uniqueness of the periodic solution are obtained; After that, by constructing a suitable Lyapunov functional, a set of easily applicable criteria is established for the global asymptotically stability of the periodic solution.
