Wandering Cauliflowers

In this paper we examine an orbit of simply connected wandering domains for the function ${f(z) = z\cos z+2\pi}$. They are noteworthy in that they are non-congruent but arise from a simple closed form function. Moreover, the shape of the wandering domains, suitably scaled, converges in the Hausdorff metric to the filled-in parabolic basin of the quadratic ${z^2+c}$ with $c=\tfrac{1}{4}$, commonly named the ``cauliflower''.
We complete our analysis by classifying the wandering domains within the ninefold framework in \cite{benini+2021}, finding they are contracting and the diameters of the wandering domains tend to zero.
To conclude we propose an expansion of the analysis to a wider family of functions and discuss some potential results.
