 the distributive property MphLee Fellow Posts: 184 Threads: 19 Joined: May 2013 05/27/2014, 12:46 PM (This post was last modified: 05/27/2014, 03:58 PM by MphLee.) Please.. can you give me a soft explaination? $f$ is meant to be a fractional (half) iterate of exp? How do you arrive at $f ( f^{\circ -1}(a) + f^{\circ -1}(b) ) = a + b$? is the starting Hypotesis? After that i can't follow the differentiation argument (my fault)...seems me that you are proving that whenerever f is an addition automorphism it is linear but is obvious that if $f(x)$ is $Cx$ for some $C$ it is an automorphism of the addition... in other words I don't get why we need such automorphism $f$...and how it helps us.
