SUMMARY

The discussion centers on the mathematical expression ##f'(\Phi(z))=\frac{df(\Phi(z))}{dz}##, where the confusion arises regarding the notation of the prime in ##z'##. Participants clarify that the prime denotes the derivative of the function ##f## with respect to the variable ##z##. The conversation also references a 1983 book, indicating its relevance to the topic at hand.

TL;DR
My question is about Eq. (3.8.12) on page 112 of this text:
https://arxiv.org/pdf/hep-th/0108200
I believe that ##f'(\Phi(z))=\frac{df(\Phi(z))}{dz}##, I get confused with the prime in ##z'## and is it really just this derivative?
I wonder how many people read this 1983 book.
