Webwhich is just a gauge transformation of a vector potential Aµ. In other words, if one couples a globally U(1) symmetric theory to a gauge ﬁeld Aµ by the covariant derivative ∂µ → Dµ ≡ ∂µ + iQAµ, one ends up with a locally symmetric U(1) theory. This way of coupling a gauge potential to a matter ﬁeld is traditionally called WebThese notes are intendedtosupplementthe lecturecourse ‘Introduction toQuan-tum Field Theory’ and are not intended for wider distribution.

WebThese notes give an in-troduction to eld theories exhibiting various types of symmetries, including Yang-Mills theory, supersymmetric eld theories, gravity, supergravity and higher-spin gauge theories. The latter are highly symmetric relativistic theo-ries conjectured to underlay quantum gravity and String Theory. Webcourse is to understand a particular instatiation of Gauge Theory, namely Seiberg-Witten (S-W) theory in di-mension 4. Most of the results we will get to arose between the years 1994 and 2004. The essential motivation behind S-W theory comes from using partial diﬀerential equations and gauge theory to classify 4 dimensional manifolds. floor consideration examples
