n维Mbius变换的基本公式与Vahlen定理——祝贺李森林教授八十大寿

On the Basic Formulas and Vahlen' s Theorem of the Mbius Transformations Acting in ■~n

建立了n维Mǒbius变换的笛卡尔矩阵表示式和克里夫特矩阵表示式的系数之间的关系.顺便给出了Vdhlen定理的证明.

This paper establishes the relations between the coefficients of Cartesian matrix representation of an orientation-preserving Mbius transformation g(x) acting in ■~n By the way, a proof of Vahlen's Theorem is given.
