On synchronized coded systems
Wolfgang Krieger
We introduce a class of codes with overlapping code words, that we call SPO-codes. The SPO-codes are related to the Markov codes that were introduced in: G. Keller, J. Combinatoria…
On the subsystems of certain sofic shifts
Wolfgang Krieger
For an aperiodic subshift of finite type and for a subshift with topological entropy less than the topological entropy of , a theorem is proved in Krieger: On the subsys…
Families of directed graphs and topological conjugacy of the associated Markov-Dyck shifts
Toshihiro Hamachi, Wolfgang Krieger
We describe structural properties of strongly connected finite directed graphs, that are invariants of the topological conjugacy of their Markov-Dyck shifts. For strongly connected…
On a class of highly symmetric Markov-Dyck shifts
Wolfgang Krieger
A class of highly symmetric Markov-Dyck shifts is introduced. Topological entropies and zeta functions are determined.
Markov-Dyck shifts, neutral periodic points and topological conjugacy
Wolfgang Krieger, Kengo Matsumoto
We study the neutral periodic points of the Markov-Dyck shifts of finite strongly connected directed graphs. Under certain hypothesis on the structure of the graphs we show, that t…
Dynamics of swelling and drying in a spherical gel
Thibault Bertrand, Jorge Peixinho, Shomeek Mukhopadhyay +1
Swelling is a volumetric-growth process in which a porous material expands by spontaneous imbibition of additional pore fluid. Swelling is distinct from other growth processes in t…
