An integrating factor matrix method to find first integrals

Autor: Saputra, K. V. I., Quispel, G. R. W., van Veen, L.

In this paper we developed an integrating factor matrix method to derive conditions for the existence of first integrals. We use this novel method to obtain first integrals, along with the conditions for their existence, for two and three dimensional

The saddle-node-transcritical bifurcation in a population model with constant rate harvesting

Autor: Saputra, K. V. I., van Veen, L., Quispel, G. R. W.

We study the interaction of saddle-node and transcritical bifurcations in a Lotka-Volterra model with a constant term representing harvesting or migration. Because some of the equilibria of the model lie on an invariant coordinate axis, both the sadd

Report

The dynamics of a low-order coupled ocean-atmosphere model

Autor: van Veen, L., Verhulst, F., Opsteegh, T.

Publikováno v: Tellus 53A, no. 5, 616-627

A system of five ordinary differential equations is studied which combines the Lorenz-84 model for the atmosphere and a box model for the ocean. The behaviour of this system is studied as a function of the coupling parameters. For most parameter valu
