This is very embarrasing. This was my thesis, and after some revisions (and procrastination), I sent it (by snail mail) to J. C. Yoccoz (who was then an editor at Inventiones), and never received any acknowledgment. It is entirely possible, perhaps probable, that I sent the paper to an outdated address. Of course I should have followed up on the paper and made inquiries, but I was young and foolish and confused.
