摘要
本文探讨S-G方程的解和E^3中负曲率曲面之间的联系,由此引出一个二阶椭园非线性偏微分方程(文中(18)式)的求解问题。
In this paper, We would try to generalize the known results on Soliton equations and psoude--sphericai surfaces due to R. Sasaki, and derive the following Proposition. Let the function φ (u, v)is a soluton of Sine--Gorden equation, if, for some function λ(u, v), the non--linear partial elliptic differential equation of order2 fuu+fvv+2Cot2 φ[ φufu + φvfv ] + λ^2e^2f- 1 =0 ……………………(*)have a solution f (u, v), then,there exist a Surface S in Ea WhoseGauss Curvature K (u, v) =-e^2f(u,v)(0 and whose the spread--anges of the asymptotic net on S are equat to 2 φ)(u, v). also, the surfaceS is of Constant Curvature iff λ (u, v) =const. We conclude from the proposition that, if the differential equation(*) has a solutioia corresponding to λ(u, v)≠const, then the Surface Srelevanced to the solution φ(u, v) of Sine--G6rden equation is non-- trivially conformal to the Pseude--spherical surface.
