Query: Stretched-exponential mixing for $\mathscr{C}^{1+\alpha}$ skew products
  with discontinuities   Consider the skew product $F:\mathbb{T}^2 \to \mathbb{T}^2$, $F(x,y)=
(f(x),y+\tau(x))$, where $f:\mathbb{T}^1\to \mathbb{T}^1$ is a piecewise
$\mathscr{C}^{1+\alpha}$ expanding map on a countable partition and
$\tau:\mathbb{T}^1 \to \mathbb{R}$ is piecewise $\mathscr{C}^1$. It is shown
that if $\tau$ is not Lipschitz-cohomologous to a piecewise constant function
on the joint partition of $\tau$ and $f$, then $F$ is mixing at a
stretched-exponential rate.
