The Cyclic Hopf H mod K Theorem

Abstract

The $H\mathrm{mod}K$ theorem gives all possible periodic solutions in a $\Gamma -$equivariant dynamical system, based on the group-theoretical aspects. In addition, it classifies the spatio temporal symmetries that are possible. By the contrary, the equivariant Hopf theorem guarantees the existence of families of small-amplitude periodic solutions bifurcating from the origin for each $\mathbf{C}-$axial subgroup of $\Gamma \times {\mathbb{S}}^1.$ In this paper we identify which periodic solution types, whose existence is guaranteed by the $H\mathrm{mod}K$ theorem, are obtainable by Hopf bifurcation, when the group $\Gamma$ is finite cyclic.
