Abstract:
The dynamics on non-hyperbolic minimal sets is investigated for non-linear competitive-cooperative tridiagonal systems in time-recurrent structures including almost periodicity and almost automorphy. With the help of exponential separation of the Floquet bundles proved in a previous work of the present authors, we prove that the skew-product flow on a minimal set $Y$ is topologically conjugate to a minimal flow in $\mathbb {R}^1\times H(f)$ (where $H(f)$ is the hull of $f$), provided that the center-space associated with $Y$ is one-dimensional. In particular, if $Y$ is uniquely ergodic, then $Y$ can be embedded into $\mathbb {R}^1\times H(f)$. We further propose a conjecture in the case that the dimension of the center-space is greater than one.References
