Nixon-Banach-Lambert-Raes tetration is analytic , simple and “ closed form “ !!
#1
Recently James Nixon posted a paper claiming analytic tetration by using a simple phi function and banach fixed point theorem !

As I commented there, I confirm this is indeed analytic !!

So it is simple (relatively easy to compute or define ) and analytic. 


But I discovered it also has a closed form more or less.  


That form uses mainly the Lambert-W and phi functions.


Hence I name this type of tetration:

Nixon-Banach-Lambert-Raes tetration 

Or in short 

NBLR tetration. 

More about that soon ! 
( I need to sleep now )

Not trying to steal too much credit by adding my name I hope.
This is mainly James Nixon’s result ofcourse. 

Although I must add it might influence questions about my sinh method. 

See also the comment I made in his thread. 

I started a new title because I wanted to highlight this wonderful result and my little contribution by noting the Lambert W connection. 

The naming ( NBLR ) is in order of importance.
