Introduction to O(N) Model & Large N Expansion

Click For Summary

Discussion Overview

The discussion revolves around the O(N) model and the large N expansion, focusing on introductory resources and literature that cover these topics. Participants seek to understand the complexity and mathematical details involved in these concepts.

Discussion Character

  • Exploratory, Technical explanation

Main Points Raised

  • One participant requests recommendations for introductory materials on the O(N) model and large N expansion.
  • Another participant suggests Sidney Coleman's book 'Aspects of Symmetry' as a valuable resource for the large-N expansion.
  • A question is raised regarding whether the suggested book includes technical steps and mathematical details.
  • A response indicates that the book is fairly advanced and may require additional effort to work through the steps, while also confirming it covers the O(N) model.

Areas of Agreement / Disagreement

There is no explicit consensus on the best introductory resource, but there is agreement that Coleman's book is relevant to the discussion.

Contextual Notes

The discussion does not clarify the specific level of mathematical detail or prerequisites needed for understanding the O(N) model and large N expansion as presented in the suggested literature.

can anyone refer me to some good introduction to this O(N) model and also large N expansion.
Thanks.

In my opinion the best book for the large-N expansion is Sidney Coleman - 'Aspects of Symmetry'

Does it contain technical steps and mathematical details also?
 
It's fairly advanced so maybe it will have to work through the steps a bit. It also contains the O(N) model.
