F Theory
Our commenter Mitchell is keen to link our mixing matrices to phenomenology from F Theory. Recall that F Theory is a dimensional theory, so for us this is the dimensions we get from counting, say, quarks, or the dimensions we get from counting marked points and holes on the three complex moduli of twistor dimension, namely , and . Anyway, lo and behold, Mottle writes today about a brand new arxiv paper on Fuzzy F Theory ... and why the number should be taken seriously (by stringers at least) as an exact coupling parameter.

To quote their abstract: "The value of is predicted to be equal to the number of fuzzy points on the internal 4-cycle." They mean . Here, the word 'fuzzy' is just a fuzzy stringy term for geometry that is not classical.
ReplyDeleteThe wrapping of branes brings to mind my all time favourite homotopy group, namely . Ah, this brings back memories. Back in, oh probably around 1996, I was proposing thesis topics to some stringy people in Australia, and I was keen to look at a topological theory that was like a 7D version of 3D Chern Simons theory. Anyway, this would have been a very interesting thing to work on, but nobody thought so at the time and I was eventually forced to leave the university in Sydney for lack of a supervisor, lol.
