Periodic solutions and almost periodic solutions for a delay multispecies logarithmic population model. (English) Zbl 1089.92038
Summary: By using the method of fixed point theory and Lyapunov functionals, a set of easily applicable criteria is established for the existence, uniqueness and global attractivity of positive periodic (almost periodic) solutions of a delay multispecies logarithmic population model.
