Abstract
We investigate the Teichmüller metric and the complex structure on the Teichmüller space \( \mathcal{T} \)(H ∞) of the universal hyperbolic solenoid H ∞. In particular, a version of the Reich-Strebel inequality for H ∞ is obtained. As a consequence, we show that the Teichmüller type Beltrami coefficients determine unique geodesics in \( \mathcal{T} \)(H ∞), and we compute the infinitesimal form of the Teichmüller metric. In addition, we show that a Beltrami coefficient is Teichmüller extremal if and only if it is infinitesimally extremal. Finally, we show that the Kobayashi metric on \( \mathcal{T} \)(H ∞) equals the Teichmüller metric.
