摘要
介绍了由任意Morita context构造高阶的Morita系统环的方法.讨论了Morita系统环上Grothendieck群K0与Whitehead群K1的相关问题.给出了Kerπ群的一个等价刻划.
A method for constructing higher order Morita context matrix rings by any Morita context is introduced.The Grothendieck group K0 and the Whitehead group K1 of the Morita context rings are discussed.An equivalent characterization of the group Kerπ is given.
