| Minimal Forbidden Patterns (2007) | |||||||||||||||
Abstract | |||||||||||||||
| We study whether the entropy (or growth rate) of minimal forbidden patterns of symbolic dynamical shifts of dimension 2 or more, is a conjugacy invariant. We prove that the entropy of minimal forbidden patterns is a conjugacy invariant for uniformly semi-strongly irreducible shifts. We prove a weaker invariant in the general case. | |||||||||||||||
