Abstract: 
In this paper, we consider and resolve a geometric problem by using &mu;(z)-homeomorphic theory, which is the generalization of quasiconformal mappings. A sufficient condition is given such that a C1-two-real-dimensional connected orientable manifold with almost positive definite metric can be made into a Riemann surface by the method of isothermal coordinates. The result obtained here is actually a generalization of Chern’s work in 1955.
