The metric conjecture for the Teichmüller-type space of routes to chaos

About 1 year old · traced to

For each route to chaos CC, let [C][C] be its boundary, namely the collection of limit dilatations of sequences drawn from the dilatation sets of the stages of CC. Let TchaosT_{chaos} be the collection of all such boundaries, and define

d([C],[C′])=inf⁡{ln⁡(K(f−1∘g)):f∈[C], g∈[C′]}.d([C],[C'])=\inf\{\ln(K(f^{-1}\circ g)): f\in[C],\ g\in[C']\}.

The function dd is already known in the paper to be symmetric and to satisfy the triangle inequality. Metric conjecture. dd is a metric on TchaosT_{chaos}. This strengthens the established pseudometric properties by asserting that distinct points have positive distance; the paper proposes a Teichmüller-theoretic approach but does not resolve the claim.
