Background Within outpatient services, a broad range of innovations are being pursued to better manage care and reduce unnecessary appointments. One of the least-studied innovations is Patient-Initiated Follow-Up, which allows patients to book appoin

In this paper, we obtain the exact rates of decay to the non-hyperbolic equilibrium of the solution of a functional differential equation with maxima and unbounded delay. We study the convergence rates for both locally and globally stable solutions.

In this paper we consider unbounded solutions of perturbed convolution Volterra summation equations. The equations studied are asymptotically sublinear, in the sense that the state-dependence in the summation is of smaller than linear order for large

In this paper we consider the rate of convergence of solutions of a scalar ordinary differential equation which is a perturbed version of an autonomous equation with a globally stable equilibrium. Under weak assumptions on the nonlinear mean revertin

This paper studies the asymptotic growth and decay properties of solutions of the stochastic pantograph equation with multiplicative noise. We give sufficient conditions on the parameters for solutions to grow at a polynomial rate in $p$-th mean and

In this paper we consider the global and local stability and instability of solutions of a scalar nonlinear differential equation with non-negative solutions. The differential equation is a perturbed version of a globally stable autonomous equation w

This paper concerns the asymptotic behaviour of solutions of functional differential equations with unbounded delay to non-equilibrium limits. The underlying deterministic equation is presumed to be a linear Volterra integro-differential equation who

We consider a system of perturbed Volterra integro-differential equations for which the solution approaches a nontrivial limit and the difference between the solution and its limit is integrable. Under the condition that the second moment of the kern

The paper studies the subexponential convergence of solutions of scalar Itô-Volterra equations. First, we consider linear equations with an instantaneous multiplicative noise term with intensity $\sigma$. If the kernel obeys \[ \lim_{t \rightarrow\i
