Eric Weinstein suggested several alterations, that have been included above: | |||
* In (ii), “vector bundle X” should be changed to principal G-bundle. | |||
* Also in (ii), “nonabelian gauge group G” should be changed to nonabelian structure group G. | |||
* In (iii), <math>\ R</math> and <math>\tilde R</math> should be (complex) linear representations of G and so they are not equivalent. | |||
* He mentioned that some info was not required, and that higgs is remarkably absent. | |||
