Abstract

For the solid torus V = S1 × and a C1 embedding f: VV given by with dϕ/dt > 1, 0 < λi(t) < 1 the attractor Λ = ∩i = 0fi(V) is a solenoid, and for each disk D(t) = {t} × (tS1) the intersection Λ(t) = Λ ∩ D(t) is a Cantor set. It is the aim of the paper to find conditions under which the Hausdorff dimension of Λ(t) is independent of t and determined by where the real numbers pi are characterized by the condition that the pressure of the function log : S1 → ℝ with respect to the expanding mapping ϕ: S1S1 becomes zero. (There are two further characterizations of these numbers.)

It is proved that (0.1) holds provided λ1, λ2 are sufficiently small and Λ satisfies a condition called intrinsic transverseness. Then it is shown that in the C1 space of all embeddings f with sup λi > Θ−2 (Θ the mapping degree of ϕ: S1S1) all those f which have an intrinsically transverse attractor Λ form an open and dense subset.
