Lit: functions whose iterates eventually identity Gottfried Ultimate Fellow Posts: 898 Threads: 130 Joined: Aug 2007 06/25/2008, 01:35 PM Hi - I just found this article, which seem to be relevant to our subject when just skimming through. Although the powertower is not mentioned this seems also to mean functions whose infinite iterations converge to a fixpoint (if I didn't misread this article) Die algebraischen Funktionen, deren Iteration die Identität liefert. Hornich, Hans in: Monatshefte für Mathematik Vol 52 Pg 311 - 322 http://gdz.sub.uni-goettingen.de/dms/res...N002469863 This is in german language. It may be as well relevant for the tetra-series-problem, since the infinite iterations to the two fixpoints are involved in computation of the series.
