一类多项式扩张的K0群

The K0 of a Coherent Polynomial Extension

  • 摘要:证明了正则稳定凝聚环上的多项式环是正则的, 并得到对于任何的正则稳定凝聚环R, 皆有K0Rt1,…,tn同构于 K0R成立

    Abstract:It is proved that the polynomial ring Rtover a regular stably coherent ring Ris also regular, and obtained that K0 Rt1,…,tnis isomorphic to K0 Rfor any regular stably coherent ring R.
