[MSE] Fixed point and fractional iteration of a map
I've asked this question few days ago on MSE, is about the behaviour of the fractional iterates when there are fixed points. I know that in this forum there was alot of works on the fixed point and stuff, by I have to admit that I can't understand alot.
The better strategy here would be to study some literature and start from 0, anyways at the moment I don't really have alot of time so I started with a very specific question.


The question is the following:

1 - If is a fixed point of the map and ..

2 - exist a map such that (aka behaves as a -iterate of )

prove that is also a fixed point of

On MSE I give a proof but I'm not sure if it is formal, if somone want to try there is a 100 reps bounty there.

PS: If my proof is correct then I guess that even , , .... exc.. are all fixed points of
