摘要
本文按照教科书对奇偶性的定义,,利用数学归纳法证明了一个n阶排列的奇偶性和其中的m阶排列的奇偶性及(n-m)阶排列的奇偶性的关系,进而将n阶行列式按其任意行组成的m阶行列式展开。
According to the definition of Odd-even of n-order p ermutation in the textbook, we have used mathematical induction to prove how the odd-even of n-order permutation is related to that of its m-order permutation a nd that of its (n-m) order permutation, furthermore an expansion of n order dete rminant is made into a summation of its m order sub determinants multiplied with their (n-m) order algebraic sub determinants.
