This is just a simple question in that area. My conjecture is that $\mu$ is not always $\sigma$-subadditive, mainly because otherwise I would have seen this statement before. The smallest possible counterexample could occur when $|X_1| = |X_2| = 3$. However I think in that case $\mu$ is $\sigma$-subadditive, but this is not so easy to check. | |
