  We extend the notions of topological stability, shadowing and persistence
from homeomorphisms to finitely generated group actions on uniform spaces and
prove that an expansive action with either shadowing or persistence is
topologically stable. Using the concept of null set of a Borel measure $\mu$,
we introduce the notions of $\mu$-expansivity, $\mu$-topological stability,
$\mu$-shadowing and $\mu$-persistence for finitely generated group actions on
uniform spaces and show that a $\mu$-expansive action with either
$\mu$-shadowing or $\mu$-persistence is $\mu$-topologically stable.
