Mixed Type Functional Differential Equations: Insight, Issues and Applications

The seminar will focus on mixed-type functional dierential equations (MTFDEs) of the form x(t)=a(t)x(t)+b(t)x(t1)+c(t)x(t+1). The emphasis of our work (to date) with MTFDEs (also referred to as forward-backward equations) has been on the development of numerical approaches to the solution of this type of equation. Alongside our continuing interest in this area we are now seeking to apply our approach in modelling applications. These equations are known to have application in nerve conduction theory, one of our current areas of investigation. Parameter estimation is a technique of interest to mathematical modellers. If the equation being used by the modeller admits small solutions (solutions that approach zero faster than any exponential) then no information is obtained about the parameters. We have successfully detected the presence of small solutions to several classes of delay dierential equations (DDEs) using a numerical approach. We discuss the potential for our work with DDEs to provide insight into the detection of small solutions to MTFDEs and present illustrative examples.
