This monograph focuses on the study of oscillation and the stability of delay models occurring in biology. The book presents recent research results on the qualitative behavior of mathematical models under different physical and environmental conditions, covering dynamics including the distribution and consumption of by: 4.

Abstract This paper is concerned with oscillatory behavior of a class of fourth-order delay dynamic equations on a time scale. In the general time scales case, four oscillation theorems.

linear delay dynamic inequality () y (t)+p(t)y(˝(t)) 0 for t 2 T and uni ed oscillation criteria of delay di erential and di erence equa-tions. In this paper, we consider the second order linear delay dynamic equation () x (t)+p(t)x(˝(t)) = 0 for t 2 T on a time scale, where the function p is rd-continuous such that p(t) > 0.

In this paper, we shall study the oscillation of all positive solutions of the nonlinear delay differential equation and about their equilibrium points.

Also, we study the stability of these equilibrium points and prove that every nonoscillatory positive solution tends to the equilibrium point when t tends to infinity.

Stability and Oscillations in Delay Differential Equations of Population Dynamics by K. Gopalsamy,available at Book Depository with free delivery worldwide. Our results extend and improve some known theorems, but also unify the oscillation of the second-order nonlinear delay differential equation with damping and the second-order nonlinear delay.

The theory of the oscillation is one of the most interesting topics for applications. In recent years, the oscillations of difference equations [1,2], dynamic equations [3,4] and delay differential. Oscillations in SIRS model with distributed delays 5 of equations for the fraction of susceptible and infectious sub-populations (bear in mind that r(t) = 1− s(t)− i(t), so that just two equations describe the dynamics): ds(t) dt = −β s(t)i(t)+βs(t− τ0)i(t− τ0), (2a) di(t) dt = β s(t)i(t)−β s(t− τi)i(t− τi).

Time delay differential equations have been helpful in the testing of algorithms for the computation of quantitative measures which can be used to characterize complex dynamics in both model equations and physical and biological systems.

One measure being intensively studied is the dimension. Periodic solutions and oscillation of discrete non-linear delay population dynamics model with external force Article (PDF Available) in IMA Journal of Applied Mathematics 70(6) .In mathematics, delay differential equations (DDEs) are a type of differential equation in which the derivative of the unknown function at a certain time is given in terms of the values of the function at previous times.

DDEs are also called time-delay systems, systems with aftereffect or dead-time, hereditary systems, equations with deviating argument, or differential-difference equations.Abstract. Chapter 4 deals with nonoscillation properties of scalar linear differential equations with a distributed delay.

It is usually believed that equations with a distributed delay, which involve differential equations with several variable delays, integrodifferential equations and mixed equations with concentrated delays and integral terms, provide a more realistic description Cited by:
