报告摘要：Mean dimension is an invariant of dynamical systems which can distinguish systems of infinite entropy.

We  introduce the  notion  of  conditional  mean  dimension for a topological dynamical system relative to a factor system.With the help of this notion, an inequality is obtained to estimate the mean dimension of the extension system. Conditional mean dimension for a $G$-extension is computed.
