摘要：An HCMU metric is an extremal Kähler metric with singularities on a compact Riemann surface. It can be regarded as a generalization of CSC(constant scalar curvature) metric. We will prove that any HCMU metric is a pullback of an HCMU metric on S^2 with only two singularities(we call it football) by a multi-valued function. Then we study the monodromy group of the multi-valued function.
