WebDefinition. A diffeomorphism : S S' between regular surfaces is called a conformal map if for all points p S and tangent vectors W1, W2 TpS we have < d p(W1) , d p(W2) > (p) = 2(p) < W 1, W2 >p, where 2 is a strictly positive smooth function on S . The surfaces S and S' are then said to be conformally equivalent. Problem 4. Webis a diffeomorphism..
