High-Order Analysis of Canard Explosion in the Brusselator Equations
International Journal of Bifurcation and Chaos
© 2020 World Scientific Publishing Company.The aim of this paper is to obtain a high-order approximation of the canard explosion in the Brusselator equations. This classical chemical system has been extensively studied but, until now, only first-order approximation to the canard explosion has been provided. Here, with the help of the nonlinear time transformation method, we are able to obtain an approximation to any desired order. Our results strongly agree with those obtained by numerical continuation.
