ProductLog

[Stan Wagon&JoanHutchinson]

This is my first posting to seqfan, prompted by a message from John
Conway....I trust it got through to the whole list...


1. ProductLog in Mathematica IS exactly LambertW

2. Sum[((-n)^(n - 1)*z^n)/n!, {n, 1, Infinity}]  is indeed the series for=

ProductLog, as Walter Meussen said.

3. Corless and Borwein (jborwein at cecm.sfu.ca, rcorless at julian.uwo.ca)
have some new results relating the series expansion for ProductLog to
Stirling's formula.....contact them for details...perhaps their preprint =
is
on a web page.
