Residual finiteness growths of virtually special groups

Let

Groups with near exponential residual finiteness growth

G

Approximating a group by its solvable quotients

G be a virtually special group. Then the residual finiteness growth of

Weakly maximal subgroups in regular branch groups

G

Local residual finiteness of abstract commensurators.

G is at most linear. This result cannot be found by embedding
