Canards at Folded Nodes
Canards Folded Nodes
2015/8/25
Folded singularities occur generically in singularly perturbed systems of differential
equations with two slow variables and one fast variable. The folded singularities can
be saddles, nodes or foci...
Singularly perturbed systems of ordinary di erential equations arise in many
biological, physical and chemical systems. We present an example of a singu-
larly perturbed system of ordinary di erenti...

This is the second in a series of papers about the dynamics of the forced van der Pol oscillator
[J. Guckenheimer, K. Hoffman, and W. Weckesser, SIAM J. Appl. Dyn. Syst., 2(2 003), pp. 1–35].
