【摘要】 对称多项式基本定理在理论上已经解决了对称多项式用初等对称多项式的多项式表出的问题 ,但具体实施这一表出并非易事 .本文给出三类对称多项式的初等对称多项式表达式 ,并给出了相应范数的计算更多还原

【Abstract】 It has been proved theoretically by the basic theorem of symmetric polynomial that any symmetric polynomial can be expressed by elementary symmetric polynomial. But this expression is not easy to write out. In this paper, the elementary symmetric polynomial expressions of three kinds of symmetric polynomial and their corresponding norm calculation is given out.更多还原
