# How do I actually derive the Griffiths inequality for critical exponents? [closed]

The Griffiths inequality for critical exponents says $$\alpha+\beta(1+\delta) \geq 2$$

I have looking for the internet for a full derivation but couldn't find anything.

• Can you give a bit more context/detail and define what each of the variables are? May 20 at 5:17
• As suggested by @G.Smith, a derivation can be found, for instance, in the book by Pathria and Beale (p. 439-441 in the third edition). May 20 at 5:49
