关于半欧氏空间之间调和同态的一些结果

摘要

Harmonic morphisms between semi-Euclidean spaces R → R is studied. Two theorems are given to construct harmonic morphisms between semi-Euclidean spaces in two ways, and Ou Yielin's corresponding results are generalized. Some interesting examples of quadratic harmonic morphisms between semi-Euclidean spaces are presented.%研究半欧氏空间R →之间的调和同态.推广了欧业林构造欧氏空间之间调和同态的方法,得出半欧氏空间之间2个相应的定理.同时,给出半欧氏空间之间二次调和同态的一些有趣的例子.
