在Loop群分解(Birkhoff分解)的基础上,给出了欧氏空间中离散常负Gauss曲率(伪球面)曲面的非线性d'Alembert公式的离散形式.并利用该公式对两个实例进行了详细的计算。
On the basis of loop group decompositions (Birkhoff decompositions), we give a discrete version of the nonlinear d’Alembert formula, a method of separation of variables of difference equations, for discrete constant negative Gauss curvature (pseudospherical) surfaces in Euclidean three space. We also compute two examples by this formula in detail.
