The present note determines the structure of the K2-group and of its subgroup over a finite commutative ring R by considering relations between R and
finite commutative local ring Ri (1 < i < m), where R Ri and K2(R) =
K2(Ri). We show that if charKi= p (Ki denotes the residual field of Ri), then
K2(Ri) and its subgroups must be p-groups. 相似文献

The present note determines the structure of the K2-group and of itssubgroup over a finite commutative ring R by considering relations between R andfinite commutative local ring Ri (1 ≤ i ≤ m), where R ≌ m i=1 Ri and K2(R) ≌ m i=1 K2(Ri). We show that if charKi = p (Ki denotes the residual field of Ri), then K2(Ri) and its subgroups must be p-groups. 相似文献
