A translation surface is a collection of polygons with edge
identifications given by translations. In spite of the simplicity of the
definition, the space of translation surfaces has connections to
different areas of math such as the moduli space of Riemann surfaces and
rational billiards in the plane.
In this talk we consider the unstable foliation, that locally is given
by changing horizontal components of period coordinates, which plays an
important role in study of translation surfaces, including their
deformation theory and in the understanding of horocycle invariant
measures. We show that measures of "large dimension" equidistribute and
give an effective rate. An analogous result in the setting of
homogeneous dynamics is crucially used in the recent effective
equidistribution results of Lindenstrauss-Mohammadi and
Lindenstrauss--Mohammadi--Wang.
