Talk:Sigma model

maths rating

I am setting this to high, given that it is the basis for many theories, including ST. 201.8.27.5 (talk) 19:35, 28 October 2008 (UTC)

Someone else set it to low. I set it to mid. 67.198.37.16 (talk) 23:24, 28 October 2020 (UTC)

complex plane

Wouldnt quantum mechanics be a sigma model from the real line to the complex plane? Or have i missunderstood something? — Preceding unsigned comment added by 82.132.244.222 (talk) 20:41, 6 July 2015 (UTC)

Lagrangian notation

Wouldn't be good to mention in what notation is the Lagrangian written? It is not the usual field theory notation. Paranoidhuman (talk) 04:04, 9 January 2019 (UTC)

TODO List

I expanded this article last month, but never finished saying what I wanted to say. This includes:

• Articulating the general case for symmetric spaces, e.g. cleanly tracking the vector and axial vector components for the chiral model.
• The above ties together the Cartan involution, the Killing fields, etc. etc.
• Commentary about anomalies
• Commentary about Dan Freed results
• More supergravity results, e.g. oxidation

Above in rough order of priority... 67.198.37.16 (talk) 18:03, 3 February 2021 (UTC)
