Hi.
Love the book!
Section 6.11 talks about inverting the function
y = x*log(x).
It doesn't mention the Lambert W function, which inverts
y = x*exp(x). Thus W(x)*exp(W(x)) = x.
The y(x) of equation 6.11.1 would then be exp(W(x)).
There are a load of references (the canonical one would be
Corless 1996).
HTH, Robinh
