• Article: Coding of substitution dynamical systems as shifts of finite type
[Hide abstract]
ABSTRACT: We develop a theory that allows us to code dynamical systems induced by primitive substitutions continuously as shift of finite type in many different ways. The well-known prefix-suffix coding turns out to correspond to one special case. We precisely analyse the basic properties of these codings (injectivity, coding of the periodic points, properties of the presentation graph, interaction with the shift map). A lot of examples illustrate the theory and show that, depending on the particular coding, several amazing effects may occur. The results give new insights in the theory of substitution dynamical systems and might serve as a powerful tool for further researches.

• Article: Bounded density shifts
[Hide abstract]
ABSTRACT: We consider subshifts of the full shift of bi-infinite sequences with alphabet \$\{ 0, 1, \ldots , n- 1\} \$ defined by not allowing the sum of finite words to exceed a value depending on its length. These shifts we call bounded density shifts. We study these shifts in detail and make a comparison on the similarities to but also differences from the well-known \$\beta \$-shifts.

Article: Minimality, transitivity, mixing and topological entropy on spaces with a free interval
[Hide abstract]
ABSTRACT: We study dynamics of continuous maps on compact metrizable spaces containing a free interval (i.e. an open subset homeomorphic to an open interval). Special attention is paid to relationships between topological transitivity, weak and strong topological mixing, dense periodicity and topological entropy as well as to the topological structure of minimal sets. In particular, a trichotomy for minimal sets and a dichotomy for transitive maps are proved.

• Article: Continuation and Bifurcation Associated to the Dynamical Spectral Sequence
[Hide abstract]
ABSTRACT: In this paper we consider a filtered chain complex C and its differential given by a connection matrix Delta which determines an associated spectral sequence (E-r , d(r)). We present an algorithm which sweeps the connection matrix in order to span the modules E-r in terms of bases of C and gives the differentials d(r). In this process a sequence of similar connection matrices and associated transition matrices are produced. This algebraic procedure can be viewed as a continuation, where the transition matrices give information about the bifurcation behavior. We introduce directed graphs, called flow and bifurcation schematics, that depict bifurcations that could occur if the sequence of connection matrices and transition matrices were realized in a continuation of a Morse decomposition, and we present a dynamic interpretation theorem that provides conditions on a parameterized family of flows under which such a continuation could occur.

• Article: A volume preserving flow with essential coexistence of zero and non-zero Lyapunov exponents
[Hide abstract]
ABSTRACT: We demonstrate essential coexistence of hyperbolic and non-hyperbolic behavior in the continuous-time case by constructing a smooth volume preserving flow on a five-dimensional compact smooth manifold that has non-zero Lyapunov exponents almost everywhere on an open and dense subset of positive but not full volume and is ergodic on this subset while having zero Lyapunov exponents on its complement. The latter is a union of three-dimensional invariant submanifolds, and on each of these submanifolds the flow is linear with Diophantine frequency vector.

• Article: Lamination languages
[Hide abstract]
ABSTRACT: Leaves of laminations can be symbolically represented by deforming them into paths of labeled embedded carrier graphs, including train tracks. Here, we describe and characterize the languages of two-way infinite words coming from this kind of coding, called lamination languages, first, by using carrier graph sequences, and second, by using word combinatorics. These characterizations generalize those existing for interval exchange transformations. We also show that lamination languages have ultimately affine factor complexity, and we present effective techniques to build these languages.

• Article: Certain properties for crossed products by automorphisms with a certain non-simple tracial Rokhlin property
[Hide abstract]
ABSTRACT: Let Ω be a class of unital C * -algebras. Then any simple unital C * -algebra A∈TA(TAΩ) is a TAΩ algebra. Let A∈TAΩ be an infinite-dimensional α-simple unital C * -algebra with the property SP. Suppose that α:G→Aut(A) is an action of a finite group G on A which has a certain non-simple tracial Rokhlin property. Then the crossed product algebra C * (G,A,α) belongs to TAΩ.

• Article: Ruelle operator with weakly contractive iterated function systems
[Hide abstract]
ABSTRACT: The Ruelle operator has been studied extensively both in dynamical systems and iterated function systems (IFSs). Given a weakly contractive IFS \$(X, \{w_j\}_{j=1}^m)\$ and an associated family of positive continuous potential functions \$\{p_j\}_{j=1}^m\$, a triple system \$(X, \{w_j\}_{j=1}^m, \{p_j\}_{j=1}^m)\$is set up. In this paper we study Ruelle operators associated with the triple systems. The paper presents an easily verified condition. Under this condition, the Ruelle operator theorem holds provided that the potential functions are Dini continuous. Under the same condition, the Ruelle operator is quasi-compact, and the iterations sequence of the Ruelle operator converges with a specific geometric rate, if the potential functions are Lipschitz continuous.

Article: Density of half-horocycles on geometrically infinite hyperbolic surfaces
[Hide abstract]
ABSTRACT: On the unit tangent bundle of a hyperbolic surface, we study the density of positive orbits (hsv)s≥0 under the horocyclic flow. More precisely, given a full orbit (hsv)s∈R, we prove that under a weak assumption on the vector v, both half-orbits (h sv)s≥0 and (hsv)s≤0 are simultaneously dense or not in the non-wandering set ε of the horocyclic flow. We give also a counterexample to this result when this assumption is not satisfied.
