摘要

R\mathscr{R} 表示 Rn\mathbb{R}^{n} 上的实多项式环。固定 m0m\geq 0,并令 A1,,AMRA_{1},\cdots ,A_{M}\in \mathscr{R}(A1,,AM)\left( A_{1},\cdots ,A_{M}\right) Cm C^{m} 闭包,此处记为 [A1,,AM;Cm] \left[ A_{1},\cdots ,A_{M};C^{m}\right] ,是所有可表为 f=F1A1++FMAMf=F_{1}A_{1}+\cdots +F_{M}A_{M}(其中每个 FiCm(Rn)F_{i}\in C^{m}\left( \mathbb{R}^{n}\right) )形式的 fRf\in \mathscr{R} 构成的理想。本文给出了一个计算 [A1,,AM;Cm]\left[ A_{1},\cdots ,A_{M};C^{m}\right] 生成元的算法。
