From permanence to total availability: a quantum conceptual upgrade
From permanence total availability quantum conceptual upgrade
2010/11/11
We consider the classical concept of time of permanence and observe that its quantum equivalent is described by a bona fide self-adjoint operator. Its interpretation, by means of the spectral theorem,...
Permanence and periodic solution for a predator-prey model with mixed-type functional response
Predator-prey model mixed-type functional response
2010/9/14
In this paper, a predator-prey model with mixed-type functional response is investigated. Sufficient conditions are derived that guarantee the permanence of the system. Meanwhile, when the system is p...
Equilibriums and permanence for an autonomous competitive system with feedback control
competitive system feedback control equilibrium stability permanence
2010/9/14
In this paper, an autonomous competitive model with feedback control is studied.
And the equilibriums of the system are discussed at first. Then the stability of equilibriums
are obtained by ODE’s s...
Permanence and extinction of an impulsive single-species model with hereditary effect
Single-species model permanence extinction delay pulse
2010/9/14
In this paper we establish an impulsive single-species model with hereditary effect. Easily verifiable criteria for permanence and extinction of system are derived, respectively. A brief discussion is...
Permanence in Nonautonomous Predator-prey Lotka-Voterra Systems
nonautonomous lotka-volterra system
2007/12/10
In this paper some easily verifiable sufficient conditions on the permanence of solutions for general nonautonomous two-species predator-prey model are established. These new criteria improve and exte...
