Abstract: | Homoclinic snake always refers to the branches of homoclinic orbits mbox{near} a heteroclinic cycle connecting a hyperbolic or non-hyperbolic equilibrium and a periodicorbit in a reversible variational system. In this paper, the normal form of a Swift-Hohenberg equation with two different symmetry-breaking terms (non-reversible term and non-k-symmetry term) are investigated by using multiple scale method, and their bifurcation diagrams are initially studied by numerical simulations. Typically, we predict numerically the existence of so-called round-snakes and round-isolas upon particular two symmetric-breaking perturbations. |
