In this paper a two-variable Minkowski projecting mapping in R~3 will be generalized to n-variable Minkowski projecting smooth immersion as :M→R~(n+1) basing on a fixed point p and n-dimension hypersurface smooth M in R~(n+1)(n≥2).

将R3中2元Minkowski投影映射推广为Rn+1(n≥2)中定点p关于n维光滑超曲面M到Rn+1的Minkowski投影浸入:M→Rn+1,得到n元Minkowski支撑函数φ(u1,u2,…,un)=‖P(u1,u2,…,un)+y0αPα-p‖,并证明当φ(u1,u2,…,un)在M和p(M)的共同临界点x0处不为零,且(bαβ)x0非奇异时,M和p(M)在x0处有共同的切空间Tx0M。

Minkowski projecting mapping Φ:M~2R~3 is confirmed as a mapping smoothly and continuously based on the expression.

由Minkowski投影映射Φ:M2R3的表达式知Φ是连续且光滑的映射;进一步推证得出当M2是R3中2维紧致凸流形和每一点x处rankxΦ=2时,(Φ,M2)是M2到R3中的2维光滑浸入,而且Φ(M2)是R3中的嵌入紧子流形。
