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

We extend the linear filtering method of Monte Carlo simulation, introduced in a previous paper, to two models where the quadratic approximation to the action does not hold. The first model considered is the quantum anharmonic oscillator with the double well potential V=(x 2 -x~)2on a time lattice o
