On a nonlinear delay population model

作者：

Highlights：

• We investigate uniform permanence of positive solutions of nonlinear delay equations.

• In several examples we give explicit estimates for lower and upper limit of solutions.

• We give conditions which imply that all solutions are asymptotically equivalent.
