Abstract:

In this paper, we study a quintic Liénard system x. = y, y. = -(a0x + a1x3 + a2x5) - (b0 + b1x2)y with 2-equivariance, arising from the complex Ginzburg-Landau equation. Although this system is a versal unfolding of the germ x. = y, y. = -a2x5 + O(x6) - (b1x2 + O(x3))y near the origin, it cannot be changed equivalently into a near-Hamiltonian system for global variables and parameters so that its dynamics cannot be studied via counting the isolate zeros of Abelian integrals as usual. We present a complete study of this system with a2 Copyright © by SIAM.
