设D是Cn+ 1中的有界区域,其中n≥ 1. D的一个极值映射φ是从单位圆盘φ:={φ ∈ C:| ξ| < 1}转化为D,使得D在沿着方向φ(0)在φ(0)处的小林度规由φ实现。我们说φ是复测地线,如果它实现了φ(φ)([Ab 2])中任意两点之间的小林距离。在20世纪80年代早期,Lempert [Lem 1 -2],Poletsky [Pol],Abate [Ab]等对极值映射和复测地线进行了基础性的研究。除此之外,Lempert还证明了具有C2,α-光滑边界的有界强凸域的极值映射是复测地线。Poletsky [Pol]证明了有界伪凸域的极值映射具有相当光滑的边界,例如C1-光滑,几乎是适当的。Lempert [Lem 1]和Poletsky [Pol]在他们的研究中导出了极值映射的欧拉-拉格朗日方程。在他90年代初的论文[Hua 1][Hua 2]中,
Let D be a bounded domain in Cn+ 1 with n≥ 1. An extremal map φ of D is a holomorphic map from the unit disk∆:={ξ∈ C:| ξ|< 1} into D such that the Kobayashi metric of D at φ (0) along the direction φ (0) is realized by φ. We say φ is a complex geodesic if it realizes the Kobayashi distance between any two points in φ (∆)([Ab2]). Fundamental work on extremal maps and complex geodesics has been done in the earlier 1980s by Lempert [Lem1-2], Poletsky [Pol], Abate [Ab], etc. Among many other things, Lempert showed that extremal maps of a bounded strongly convex domain with a C2, α-smooth boundary are complex geodesics. Poletsky [Pol] showed that extremal maps of a bounded pseudo-convex domain with a reasonably smooth boundary, say C1-smooth, are almost proper. Both Lempert [Lem1] and Poletsky [Pol] derived the Euler-Lagrange equations for extremal maps in their considerations. In his paper in the earlier 1990s [Hua1][Hua2], motivated by
