 Real and complex behaviour of the base change function (was: The "cheta" function) sheldonison Long Time Fellow Posts: 641 Threads: 22 Joined: Oct 2008 08/13/2009, 12:49 AM (08/12/2009, 08:59 PM)bo198214 Wrote: Actually I am somewhat confused about the continuation of $f_n = \log_a^{[n]}\circ \exp_b^{[n]}$ for some $n$ from the real axis to the complex plane (via the method described by Jay some posts ago, i.e. considering a/the path $\gamma$ from a point on the real axis to $z$, looking at its image under $\exp_b^{[n]}$ and determine the value of the subsequently following logarithms by their continuation along the image of that path). Has anyone a clear view to which points $f_n$ can be continued, is it even entire?Me too, I'm making progress on n=5,6,7 ... I think the answer will eventually come out and it will be very interesting, but I don't have enough nearly enough time to do the problem proper diligence this week. Perhaps f will even converge as n increases to infinity, just as the function converges on the real number line.... - Shel « Next Oldest | Next Newest »
