Description
Weyl invariance can be used as a principle for constructing
not only conformally invariant massless physical theories, but also
massive, partially massless and gauge invariant ones. We present
"Tractor Calculus"--which arose in conformal geometry--as a description
of Weyl invariance in physics. We use this calculus to give
new descriptions of a range of fundamental physical theories.
