摘要: 证明Moulin Ollagnier和Nowicki构造的四元多项式代数上的一个单项导子没有Darboux多项式当且仅当其常数环是平凡的.

关键词: Darboux多项式, 导子, 常数环, 单项导子

Abstract: The author proved that a monomial derivation, which was constructed by Moulin Ollagnier and  Nowicki in the polynomial algebra of four variables, has no Darboux polynomials if and only if its ring of constants was trivial.

Key words: monomial derivation; , Darboux polynomial; ring of constants, derivation
