M ay 2 00 4 DIMENSION GROUPS FOR INTERVAL MAPS

نویسنده

  • Fred Shultz
چکیده

With each piecewise monotonic map τ of the unit interval, a dimension triple is associated. The dimension triple, viewed as a Z[t, t −1 ] module , is finitely generated, and generators are identified. Dimension groups are computed for Markov maps, unimodal maps, multimodal maps, and interval exchange maps. It is shown that the dimension group defined here is isomor-phic to K 0 (A), where A is a C*-algebra (an " AI-algebra ") defined in dynamical terms.

1 1 M ay 2 00 4 EXTENSION DIMENSION AND QUASI - FINITE CW - COMPLEXES

We extend the definition of quasi-finite complexes by considering not necessarily countable complexes. We provide a characterization of quasi-finite complexes in terms of L-invertible maps and dimensional properties of compactifications. Several results related to the class of quasi-finite complexes are established, such as completion of metrizable spaces, existence of universal spaces and a ve...

M ay 2 00 9 Monotonicity of entropy for real multimodal maps ∗

In [16], Milnor posed the Monotonicity Conjecture that the set of parameters within a family of real multimodal polynomial interval maps, for which the topological entropy is constant, is connected. This conjecture was proved for quadratic by Milnor & Thurston [17] and for cubic maps by Milnor & Tresser, see [18] and also [5]. In this paper we will prove the general case.

1 M ay 2 00 4 Birational geometry of Fano direct products

Combining the connectedness principle of Shokurov and Kollár with the technique of hypertangent divisors, we develop a new technique of studying birational maps of natural Fano fiber spaces. We prove that the only structures of a rationally connected fibration on direct products of typical Fano varieties are projections onto the factors. In particular, the groups of biregular and birational sel...

M ay 2 00 4 UNIVERSAL ABSOLUTE EXTENSORS IN EXTENSION THEORY

Let L be a countable and locally finite CW complex. Suppose that the class of all metrizable compacta of extension dimension ≤ [L] contains a universal element which is an absolute extensor in dimension [L]. Our main result shows that L is quasifinite.
