“…The question of which dynamical systems have ergodic invariant measures of full Hausdorff dimension has generated substantial interest over the past few decades, see e.g. [4,9,17,18,21,24,25,27,30,31,32,33,42,45,52,55], as well as the survey articles [7,13,22,51] and the books [5,6]. Most of the results are positive, proving the existence and uniqueness of a measure of full dimension under appropriate hypotheses on the dynamical system.…”
