| Abstract: | Ecologic model of interaction of two species with nonuniform density distribution, which is defined by a partial functional differential equations system, is discussed. By using time lagging functional differential inequality, the oscillations of time lagging ecologic model is investigated and a simple sufficiency criterion of oscillation of the solution about the positive equilibrium mode is obtained. |
