Establish the theorem that any two-dimen sional riemann manifold is conformally flat in the case of a metric of signature 0, i. c. at any point the metric can be reduced to the diagonal form (+1,-1) say. [hint: use null curves as coordinate curves, that is, change to new co ordinates satisfying and show that the line element reduces to the form and finally introduce new coordinates ! (i+ v)
