Check out Irving Kaplansky, Elementary divisors and modules, Trans. Amer. Math. Soc. 66 (1949), 464–491. MR 0031470 (11,155b). I'm not up to speed on the details for the second half, either. But they are both well-known and I suspect have been streamlined. And, for that matter, what I'm suggesting may be overkill, and there could be an alternative approach. This is just the first method I thought of. | |
