Weyl transformation

In theoretical physics, the Weyl transformation is a local rescaling of the metric tensor:

The invariance of a theory or an expression under this transformation is called the Weyl symmetry. It is an important symmetry in conformal field theory - for example a symmetry of the Polyakov action.
