Jul 16, 2013 at 3:09 | comment | added | Alexander Pruss | Actually, there is no way the Parikh and Parnes construction could generalize to $\mathbb R^2$, since it requires constructing a finitely additive hyperreal-valued measure that is almost invariant in the sense that $(\mu(\rho A)-\mu(A))/\mu(A)$ is infinitesimal for non-empty $A$ and isometry $\rho$. But such a measure would rule out bounded paradoxical subsets. | |
