Sep 1, 2014 at 2:04 comment added Lubin @WillJagy, the $p$-adic situation is most nearly parallel to the last clause in your response to my comment. (But not precisely!) Anyhow, this is a case where $p$-adic analysis is much less deep than complex.
Aug 31, 2014 at 19:34 comment added Gottfried Helms Everything is fine. Thank you very much!
Aug 31, 2014 at 19:01 comment added Will Jagy @GottfriedHelms, got your message and sent the two jpegs in reply. Hope you got them.
Aug 31, 2014 at 16:23 comment added Will Jagy @GottfriedHelms, I cannot find your email, but if you look at my profile and then look me up at the CML ams.org/cml and use the gmail address, just send me a short message so I have your address. Meanwhile, I put an excerpt with a few more pages at zakuski.utsa.edu/~jagy/other.html under the name K_C_G_book_excerpts.pdf , the jpeg will just be a little better organized for my purposes
Aug 31, 2014 at 6:53 comment added Gottfried Helms Please let me see your jpegs. I think my email occurs in my profile-page.
Aug 30, 2014 at 21:27 comment added Will Jagy @Lubin, thanks. Reminds me of the results of Baker and his student Liverpool, (and evidently Ecalle, independent) that either a function has no fractional iterates, or a $1/n$th fractional iterate and nothing smaller, or a $w$-th iterate for any nonzero complex number $w,$ in which case the thing was conjugate to a Moebius transformation in the first place.
Aug 30, 2014 at 21:20 comment added Lubin It’s not in any sense a deep fact or result, but the corresponding $p$-adic question for the $p$-adic analytic function $x+x^2$ is easy to solve. The $1/n$-th iterate exists and is analytic in the open unit disk of $\mathbb C_p$ as long as $n$ is prime to $p$.
