Permanence of a discrete predator-prey system with nonmonotonic functional responses and endless delay
Journal Title: Карпатські математичні публікації - Year 2015, Vol 7, Issue 1
Abstract
A discrete-time analogue of predator-prey model with nonmonotonic functional responses and endless delay is considered in the paper. We investigate the question of obtaining conditions of permanent behavior of the dynamic model. The condition of permanence provides the limiting of the solutions but it requires the positiveness of the solutions. Sufficient conditions of permanence are obtained when the functional response function is nonmonotonic. The methods based on the estimation theorems are used to receive the sufficient permanent conditions of the solutions. These results are applied to some special population model with endless delay, some new results are obtained.

Pointwise stabilization of the Poisson integral for the diffusion type equations with inertia
In this paper we consider the pointwise stabilization of the Poisson integral for the diffusion type equations with inertia in the case of finite number of parabolic degeneracy groups. We establish necessary and sufficie...
Application of the functional calculus to solving of infinite dimensional heat equation
In this paper we study infinite dimensional heat equation associated with the Gross Laplacian. Using the functional calculus method, we obtain the solution of appropriate Cauchy problem in the space of polynomial ultradi...
k-bitransitive and compound operators on Banach spaces
In this this paper, we introduce new classes of operators in complex Banach spaces, which we call k-bitransitive operators and compound operators to study the direct sum of diskcyclic operators. We create a set of suffic...
Wiener weighted algebra of functions of infinitely many variables
In this article we consider a weighted Wiener type Banach algebra of infinitely many variables. The main result is a description of the spectrum of this algebra.
Approximation of capacities with additive measures
For a space of non-additive regular measures on a~metric compactum with the~Prokhorov-style metric, it is shown that the~problem of approximation of arbitrary measure with an~additive measure on a~fixed finite subspace r...
