The discussion centers on the derivative notation in the context of the equation f'(\Phi(z)) = df(\Phi(z))/dz. Participants express confusion regarding the meaning of the prime symbol in z' and its implications for derivatives. The conversation also touches on the relevance and readership of the 1983 book mentioned, indicating a potential gap in understanding its concepts. Clarification on the derivative notation is sought to enhance comprehension of the mathematical principles involved. The exchange highlights the importance of clear notation in mathematical discussions.

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.
 

Thread 'Dasgupta et al., What is the alternative to a unique dS vacua?'

I thought I would start a thread, as as spinoff to perhaps highlight and contemplate of that the ideas in the paper mitchell porter pointed to means. I just started to sniff it.. and wrote in the other thread "How to fix Relativistic QM so it's consistent?" Indeed fixing relativity and how to understnad equivalences, seems to be the central issue of the below paper. ----------------------------------------------------------------- Huge paper, I havent ready it through fully but skimmed...
