The Hausdorff Dimension of Non-Uniquely Ergodic directions in $\mathcal{H}(2)$ is almost everywhere $1/2$

Abstract

We show that for almost every (with respect to Masur-Veech measure) $\omega \in \mathcal{H}(2)$, the set of angles $\theta \in [0, 2\pi)$ so that $e^{i\theta}\omega$ has non-uniquely ergodic vertical foliation has Hausdorff dimension (and codimension) $1/2$.
