《群的上同调与代数K-理论》内容：Cohomology of groups is a fundamental tool in many subjects in modernmathematics. One important generalized cohmnology theory is the algebraic Ktheory,and algebraic K-groups of rings such as rings of integers and group ringsare important invariants of the rings. They have played important roles in algebra,geometric and algebraic topology, number theory, represe...(展开全部)
