Frans H. van Eemeren,Rob Grootendorstons is very different in the cases 0<α<1/2 and 1/2≤α<1. In the second case exists as solution y. for all n only y.=0, but there exist unboundedly increasing solutions for sufficiently large n. Numbers and graphs are given for some special values of a and the equation (above)is compared with the differential equation y′(x)=−cy(αx).

E.g. they concern the regulation of red blood cell populations , , excitatory-inhibitory neural interactions , , , regulation of enzyme synthesis , respiratory control circuits , and modeling of commodity cycles .

Applications of Reaching Definition Analysisform dy(t)/dt = ω.y(t) + ω.y(t−ω) where ω., ω. and ω are constants (ω>0). By generalizing the conventional predictor-corrector methods it is possible to improve the stability region in the (ω.Δt, ω.Δt) — plane considerably. In particular, methods based on extrapolation-predictors and backward differentiation- correctors are studied.

Troubleshooting: Qualification Problem,ets vollständig in Operatoren der Ordnung 1 faktorisiert werden. Eine solche Zerlegung ist in den meisten Fällen weder eindeutig noch kommutativ. Bei der Behandlung von Randwertaufgaben mit Differenzengleichungen kann man sich häufig derartige Faktorisierungen zunutze machen. Es werden hier mehrere Typen von Randwerten behandelt.

https://doi.org/10.1007/1-4020-3069-XThis paper is concerned with a general diffusion model which is described by a system of linear differential equations. Under certain conditions the existence of positiv periodic solutions is shown, if the coefficients and the right-hand side of the system are periodic.
