Circularity and repetitiveness in non-injective DF0L systems
Herman Goulet-Ouellet, Karel Klouda, Štěpán Starosta
We study circularity in DF0L systems, a generalization of D0L systems. We focus on two different types of circularity, called weak and strong circularity. When the morphism is inje…
Stability properties for subgroups generated by return words
France Gheeraert, Herman Goulet-Ouellet, Julien Leroy +1
Return words are a classical tool for studying shift spaces with low factor complexity. In recent years, their projection inside groups have attracted some attention, for instance…
Algebraic characterization of dendricity
France Gheeraert, Herman Goulet-Ouellet, Julien Leroy +1
Dendric shift spaces simultaneously generalize codings of regular interval exchanges and episturmian shift spaces, themselves both generalizations of Sturmian words. One of the key…
