An -adic characterization of minimal subshifts with first difference of complexity
arXiv:1305.0434
Abstract
In [Ergodic Theory Dynam. System, 16 (1996) 663--682], S. Ferenczi proved that any minimal subshift with first difference of complexity bounded by 2 is -adic with $\card S \leq 3^{27}$. In this paper, we improve this result by giving an -adic charaterization of these subshifts with a set of 5 morphisms, solving by this way the -adic conjecture for this particular case.
