The possibility of branching processes for classical strings is investigated on the basis of the Nambu-Goto action. We parametrize the world sheet by a Riemann surface M and introduce a degenerate, semi-Riemannian metric B on M. Well-known results about the conformal group Diff(S t ) รDiff(S l) are
