comment Lower branch of Lambert W function in mathematica
I'm sure this works, but unfortunately blochwave gave a much easier solution in the comments :). Thanks anyway.

comment Lower branch of Lambert W function in mathematica
Thank you! You are absolutely right. How stupid of me to miss this. I tried indices k=1,2,..., got some complex result and concluded that this is not what I want. Indeed, k=-1 seems to be the way to go (although I don't really understand this indexing).

Thanks. I finally got around to actually trying this and it works nicely!

comment Strange NSum behavior for slightly larger number of terms
What is interesting is that even for a HUGE number of terms (I tried with 10^6), specifying the method gives the solution much faster than the default option.

comment Strange NSum behavior for slightly larger number of terms
Thank you. Using the WynnEpsilon method seems to do the trick. Apparently NSum, by default, changes the algorithm when some number of terms is reached and it seems that the heuristic that is used to determine this algorithm fails for some reason.

comment How to simplify to form without imaginary unit
Nevermind, I figured out your code. I still have to figure out how to repair the wrong result for certain arguments. It probably has something to do with choosing the wrong branch of arctan or something.
