Popis:	Using the properties of conformal immersions (of world sheets into space-time target manifolds) a string effective lagrangian — valid for any genus — is derived. We contrast our results with those derived via the usual renormalization group approach and we get an interpretation of the Zamolodchikov’s c-theorem. (It is essentially a criterion for the existence of conformal immersions.) Finally, we discuss the restrictions our formalism imposes on the (structure and dimensions of) space-time.
