保角映射的二阶导数和曲率之间的联系已经以多种方式使用。在这篇注记中,我们给出了一个内在的提法,这是一种施瓦茨引理双曲曲率。在全文中,D将表示C中具有至少两个边界点的单连通域,并且D(> i)= xD(> i)将表示在D的双曲度量XD \ dz \中测量的在ZE y处的D中的光滑曲线y的测地曲率(常曲率-1)。
The connection between the second derivative of a conformal mapping and curvature has been used in a number of ways. In this note we give an intrinsic formulation of this as a kind of Schwarz lemma for hyperbolic curvature. Throughout, D will denote a simply connected domain in C with at least two boundary points and D(> i) = xD( > i) will denote the geodesic curvature of a smooth curve y in D at ZE y measured in the hyperbolic metric XD \ dz \ of D (constant curvature — 1).
