Mathematical competitive models on the trophic resource

The authors have developed mathematical models of operational and interference competition on a linear range based on the systems of equations with distributed parameters. They also have conducted an analysis of stationary states stability. It is shown that the operational competition on the restored trophic resource does not lead to the disappearance of one of the populations due to competition. The model of interference competition contains various options for the effects of competition between the two populations. In both models, for populations with a small number of individuals, the influence of competition is not significant. The assessment of the distribution rates of small populations on the range is given, and the conditions for the existence of an autowave solution on an unbounded straight line are obtained. In order to construct a numerical solution of a boundary value problem for a system of nonlinear differential equations, they have used the grid method with software implementation in the programming environment of the Matlab environment. Numerical results are consistent with analytical results on fine grids.
