For infinite Subshifts of Finite Type (SFT) and for DTDS on intervals. His main research topic is Ergodic Theory. by its iterated application starting from a given initial state. Toshihiro Hamachi is an Emeritus Professor at Kyushu University, Japan. One is the Dyck shift and the other is the Fibonacci- Dyck shift. In this talk as a target space we deal with two prototype subshifts in a certain class of subshifts which are quite different from SFT. It says that embedding is governed by two conjugacy invariants, the number of periodic points for a short period and topological entropy. When the target is an SFT too, there is a beautiful theorem known by W.Krieger to give an embedding condition. We are concerned with embedding of SFT's as a source in order to understand randomness of the target. In particular if the homeomorphism is onto, it is said to be a conjugacy. A homeomorphism from a subshift into another subshift is called an embedding if it intertwines the shift mappings. Note that both memory and anticipation can be either positive or negative.

If we can choose m and a so that -mar\geq 0, we say that F is a radius- r CA. The three orbits lie allin di erent planes, whi h interse t only in the origin. In particular we prove existence of a finite collection of disjoint attracting. If XY and X is a subshift, we say that F is a cellular automaton (CA). The shift mapping itself is also called a subshift. We clarify the dynamics for an open and dense subset of such skew products. The shift mapping is defined on the space and turns out a homeomorphism. Namely two such sequences of the subshift are close if on a long time interval including time 0 they coincide. A subshift is endowed with the natural compact metric topology. It is known from various points of view that SFT's are quite random. When the set of forbidden words is finite, the subshift is called a shift of finite type (SFT). Show that a system (X f) is topologically conjugate to a subshift if and only if Xis totally disconnected and (X f) is expansive. Sidequest: A system (X f) is called expansive if there exists >0 such that, for 圆yin X, supd(fnx fny) >. ![]() Given a finite alphabet the space of bi-infinite sequences of letters chosen from the alphabet is called a subshift when there is a set of words of the alphabet called forbidden words which do not appear in the sequences. A subshift consists of the pair (X ), where X Q n2Z Ais a closed -invariant subset.
