Actions for the Bosonic String with the Curved Worldsheet

Understand

At first we introduce an action for the string, which leads to a worldsheet that always is curved.

For this action we study the Poincar\'e symmetry and the associated conserved currents.
Then, a generalization of the above action, which contains an arbitrary function of the two-dimensional scalar curvature, will be introduced.
An extra scalar field enables us to modify these actions to Weyl invariant models.
