Steinberg群中的H元素和W元素

摘要

Two special types of elements in the Steinberg group over an arbitrary ring were investigated,which contributes to the estimation of the K2 of a ring.In particular,some new results concerning the K2 of a ring with stable range 1 was given.%研究了任意环的Steinberg群中的两类特殊的元素,这有助于估计环的K2群.特别地,给出了一些关于稳定秩1环的K2群的新结果.
