郑骞 , 唐国平 . K2(Z[(Cp)2×Cpn])p-秩的一个下界[J]. 中国科学院大学学报, 2015 , 32(2) : 155 -157 . DOI: 10.7523/j.issn.2095-6134.2015.02.002
First, we reduce the calculation of K2(Z[(Cp)2×Cpn])p to estimation of an exact sequence. Then, we get a higher bound of p-rank of SK1(Z[G], pZ[G]). Finally, we get a lower bound of p-rank of K2(Z[(Cp)2×Cpn]).
