报告摘要：Algebraic K-theory which comes from algebraic geometry and geometry topology, has important applications in number theory, algebraic topology and operator algebra. The integral group ring ZG of Milnor's K_2-group, is closely related with the pseudo-isotopy problems in differential topology, while to determine the explicit structure of K2(Z[G]) is quite difficult, one can estimate the size of K_2(Z[G]) via computing K_2 of some finite group algebras. In this talk, I will briefly introduce Milnor's K_2-group and the latest progress on the structures of K_2 of finite group algebras and integral group rings.
