Transitive cylinder flows whose set of discrete points is of full Hausdorff dimension

2013

For each irrational α ∈ [0, 1) we construct a continuous function f : [0, 1) → R such that the corresponding cylindrical transformation [0, 1) × R ∋ (x, t) → (x + α, t + f (x)) ∈ [0, 1) × R is transitive and the Hausdorff dimension of the set of points whose orbits are discrete is 2. Such cylindrical transformations are shown to display a certain chaotic behaviour of Devaney-like type.

An invariant of basic sets of Smale flows

Ergodic Theory and Dynamical Systems, 1997

We consider one-dimensional flows which arise as hyperbolic invariant sets of a smooth flow on a manifold. Included in our data is the twisting in the local stable and unstable manifolds. A topological invariant sensitive to this twisting is obtained.

The topology and dynamics of flows

Open Problems in Topology II, 2007

After a brief survey of various types of flows (Morse-Smale, Smale, Anosov, & partially hyperbolic) we focus on Smale flows on S 3. However, we do give some consideration to Smale flows on other three-manifolds and to Smale diffeomorphisms.

Empty Interior Recurrence for Continuous Flows on Surfaces

2010

In this paper we characterize topologically the empty interior subsets of a compact surface S which can be ω-limit sets of recurrent orbits (but of no nonrecurrent ones) of continuous flows on S. This culminates the classification of ω-limit sets for surface flows initiated in [

Every nonsingular C1 flow on a closed manifold of dimension greater than two has a global transverse disk

Topology and its Applications, 2004

We prove three results about global cross sections which are disks, henceforth called global transverse disks. First we prove that every nonsingular (fixed point free) C 1 flow on a closed (compact, no boundary) connected manifold of dimension greater than 2 has a global transverse disk. Next we prove that for any such flow, if the directed graph G h has a loop then the flow does not have a closed manifold which is a global cross section. This property of G h is easy to read off from the first return map for the global transverse disk. Lastly, we give criteria for an "M-cellwise continuous" (a special case of piecewise continuous) map h : D 2 → D 2 that determines whether h is the first return map for some global transverse disk of some flow ϕ. In such a case, we call ϕ the suspension of h.

Geometry of minimal flows

Topology and its Applications, 2006

Our main result is that for a minimal flow ϕ on a compact manifold M, either M is a torus and the flow is topologically conjugate to an irrational flow, or M is not a torus and every parametrization of ϕ has sensitive dependence on initial conditions. Our results depend heavily on the work of Lopez and Candel.

An example of a local flow on a manifold

Proceedings of the American Mathematical Society, 1974

Lctp be a point of a smooth n-dimensional manifold. If n is even it is easy to construct a local flow about p such that p is an isolated critical point and no orbit except the stationary one at/? has/» as a limit point. We call such a flow a nonnull flow about p (NN-flow). Mendelson has conjectured that NN-flows do not exist on odd dimensional manifolds. We show that Mendelson's conjecture is false by constructing an NN-flow on any smooth manifold whose dimension is an odd integer exceeding one.
