TLDR
In this paper, the authors considered non-autonomous (1.2) third-order differential equations, where a(t, b(t)y c(t), g, h, p are continuous real-valued functions depending only on the arguments shown.
Abstract
(1.2) x+a(t)f(x, Λ, x)x+b(t)g(x9 x)+c(t)h(x) = p(t, x, i, x) where a(t), b(t)y c(t) are positive continuously differentiate and /, g, h, p are continuous real-valued functions depending only on the arguments shown, and the dots indicate the differentiation with respect to t. The asymptotic property of solutions of third order differential equations has received a considerable amount of attention during the past two decades, particularly when (1.2) is autonomous. Many of these results are summarized in [11]. A few authors have studied non-autonomous third order differential equations. K. E. Swick [13] considered the following equations

Avian-human influenza epidemic model.

TL;DR: A mathematical model is proposed to interpret the spread of avian influenza from the bird world to the human world and suggests that the authors cannot feel relieved although the total infected humans are kept at low level.

On the uniform ultimate boundedness of the solutions of certain third order differential equations

TL;DR: In this paper, the authors considered the boundedness of solutions of (1.1) and (2.2) in the case a(t) = bt = ct = 1, assuming one of the following conditions on p t and p t, x, y, z:

On the asymptotic behavior of the solutions of third order delay differential equations

TL;DR: By constructing a Lyapunov functional, this paper obtained sufficient conditions which guarantee the stability and boundedness of solutions for some nonlinear differential equations of third-order with delay, which improved and generalize existing results in the relevant literature of nonlinear third order differential equations.

Global stability of a generalized epidemic model

TL;DR: The competitive exclusion principle is one of the most interesting and important phenomena in both theoretical epidemiology and biology as discussed by the authors, and it was shown that the equilibrium in which only the strain with the maximum basic reproductive number exists is globally asymptotically stable by using an average Lyapunov function theorem and some dynamical system theory.

Stability results for the solutions of some third and fourth order differential equations

TL;DR: In this paper, conditions under which solutions of the equations (1) and (2) of § 1.1 tend to zero as t → ∞ were investigated, where t is the length of the shortest path.
