Unfortunately, not much to report mathematically. 4-d case is now totally solved (modulo my adviser checking it). H

Here's what I'm dealing with:

Consider an arbitrary homomorphism from S1 into S3xS3xS3xS3 = G is given by z -> (za, zb, zc, zd).

I can use this to define an action of S1 on S3xS3 via z*(p,q) = (za p z-c, zbqz-d)

Now, it's clear that the ( Read more... )
