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
