报告摘要：Mean dimension is a newly emerging topological invariant of dynamical systems, which originates with Misha Gromov around 2000 with a view towards geometric analysis, and which is closely connected to the embedding problem. I will present in my talk a brief introduction to mean dimension and recent progress of the embedding problem. Further, as well as giving the exact value of their mean dimension I shall provide complete classification, under the action of translation, for Bernstein spaces, which were heavily used in signal analysis and which have deep application to the embedding problem.
