 Real and complex behaviour of the base change function (was: The "cheta" function) bo198214 Administrator Posts: 1,386 Threads: 90 Joined: Aug 2007 08/15/2009, 05:36 PM (This post was last modified: 08/15/2009, 05:37 PM by bo198214.)

Quote:For a=eta, b=e, anywhere that the exp^[n-2](x) is equal to -1, we will have a singularity. The double logarithm of the double exponentiation, in the respective bases, will be 0. These are the singularities induced by $f_3$. Quote:This makes me wonder, then: for any given n, there are singularities near the real line, and as n increases, these singularities get arbitrarily close. Can you make a picture for those that dont currently sit down with a computer algebra system computing exactly this? Imho the $\log^{[n-2]}(-1)$ converges to the upper primary fixed point of $\exp$. So why should they come arbitrarily close to the real axis? « Next Oldest | Next Newest »
