摘要: 以半单环和阿丁环为桥梁,构造了SF环的若干个局部化条件;在此基础上,把局部环的经典刻画结论推广到SF环上;进一步得到了SF环局部化条件下的K0群的性质;最后,讨论了SF环局部化条件下的总体维数.

关键词: SF环, 局部化, 半单环, 阿丁环, K0群, 总体维数

Abstract: Taken Artin ring and semisimple ring as bridges,some localization conditions of SF-ring are constructed for extending the classical characterization of local ring to SF-ring.The properties of groups under the condition of SF-ring localization are further obtained.Finally, the overall dimension of SF-ring localization is discussed.

Key words: SF-ring, localization, semi-simple ring, Artin ring, K0 group, general dimension
