Relative topological entropy and relative mean dimension of induced factors

We study the relation of relative topological entropy and relative mean dimension between a factor map and its induced factor map for amenable group actions.

On the one hand, we prove that a factor map has zero relative topological entropy if and only if so does the induced factor map.

On the other hand, we prove that a factor map has positive relative topological entropy if and only if the induced factor map has infinite relative mean dimension.
