 using sinh(x) ? tommy1729 Ultimate Fellow Posts: 1,358 Threads: 330 Joined: Feb 2009 11/26/2015, 11:56 PM There are many ways to solve f(f(x)) = exp(x) or g(g(x)) = 2sinh(x). If g < f then g is uniquely so. Also using the 2sinh method on g gives us f. NOTICE it is impossible to directly solve for g in the 2sinh method. So we must use g < f. This implies a bijection between g and f , by the 2sinh or equivalently the inequality. Since there exist both analytic half iterates for both 2sinh and exp , for Every f there is a g and vice versa , we get the next BIG conclusion ; There MUST exist analytic solution of type 2sinh method. --- That is nice. But one wonders if f and g related as above must 1) both be analytic or both not. ? In other words is the bijection actually univalent ? I kinda repeat myself , but I assumed it belongs here better , and it was not understood by most. Regards tommy1729 « Next Oldest | Next Newest »
