comment Prove that there exists a sequence of compact sets $K_1\subset K_2\subset…\subset A$ such that $\mu(A-\cup_{j\ge1}K_j)=0$.
It's in your assumption: $K_1 \subset K_2 \cdots$.

comment Verifying properties of a group action
Maybe our definitions are equivalent. If we have a group action then a function $f:X \to Y$ is said to be invariant if for any two points on the same orbit then $f(x)=f(y)$.

Could you elaborate on that? I think I'm visualizing this all wrong. Also, I don't see how that computation shows that this function is an invariant.
