<p>[01:22:20] So $$2^{14}$$ over $$2^7$$ is $$128$$, so we have a map into a structured group of $$U(128)$$

<p>[01:22:36] At least in Euclidean signature. We can get to mixed signatures later. From that, we can form the associated bundle, $$\gamma^{\inf}(P_{U_8}) \cross_{ad}\U{$})$$.

<p>[01:22:54] And sections of this bundle are either, depending upon how you want to think about it, the gauge group, $$H$$ or $$\Xi$$, a space of sigma fields. Nonlinear.
