我们考虑一个任意的黎曼曲面X,它可能具有无穷大的双曲面积。双曲度量的Liouville测度定义了X的万有覆盖X~的测地线空间G(X~)上的测度。当我们改变黎曼曲面结构时,这给出了从X的Teichmuller空间到G(X~)上Hölder分布的Fréchet空间的嵌入。我们证明了嵌入是连续可微的。特别地,我们得到了切映射的显式积分表示。2000年数学科目分类30 F60、32 G15(小学)、46 F99(中学)。
We consider an arbitrary Riemann surface X, possibly of infinite hyperbolic area. The Liouville measure of the hyperbolic metric defines a measure on the space G(X~) of geodesics of the universal covering X~ of X. As we vary the Riemann surface structure, this gives an embedding from the Teichmuller space of X into the Fréchet space of Hölder distributions on G (X~) . We show that the embedding is continuously differentiable. In particular, we obtain an explicit integral representation of the tangent map. 2000 Mathematics Subject Classification 30F60, 32G15 (primary), 46F99 (secondary).
