We have simulated the Oregonator by “shift type mapping” functions which approximate the strange attractor of the Oregonator (a system governed by a set of non-linear differential equations) exerted by an external periodic force. We have reproduced fairly well the bifurcation and the sequential appearance of the periodic π(m) modes and πp,q(m, m+1) modes as well as chaotic modes. The theoretical prediction of the oscillation modes using a piecewise linear mapping function agrees qualitatively with the results of the Oregonator and those using other mapping functions.
