The cost of a group is a dynamical version of the rank gradient. Similarly, the integral foliated simplicial volume of a manifold is a dynamical version of the stable integral simplicial volume. In both cases, the link is the profinite completion of the (fundamental) group.

In this talk, I will survey this analogy between group theory and manifold topology and how integral foliated simplicial volume can be viewed as a geometric refinement of cost.
