    Abstract

    Recently, Einsiedler and the authors provided a bound in terms of escape of mass for the amount by which upper-semicontinuity for metric entropy fails for diagonal flows on homogeneous spaces (Formula presented.), where (Formula presented.) is any connected semisimple Lie group of real rank one with finite center, and (Formula presented.) is any non-uniform lattice in (Formula presented.). We show that this bound is sharp, and apply the methods used to establish bounds for the Hausdorff dimension of the set of points that diverge on average.
