本文描述了一种确定嵌入伪欧氏流形M4+n中的时空V4的法向量的算法。利用代数计算系统REDUCE,给出了嵌入6维伪欧氏流形的Schwarzchild时空几何的算法的一个应用。
英文摘要:
In this paper we describe an algorithm to determine the vectors normal to a space-time V4 embedded in a pseudo-Euclidean manifold M4+n. An application of this algorithm is given considering the Schwarzchild space-time geometry embedded in a 6 dimensional pseudo-Euclidean manifold, using the algebraic computing system REDUCE.
