摘要
本文主要介绍了低阶K群K_0,K_1,K_2及与它们相关的Bass-Quillen猜测、Birch-Tate猜测研究的最新进展.K_0与K_1方面主要通过对Bass~Quillen猜测研究说明K_0,K_1的作用,同时也给出了一些多项式环上投射模自同构群的计算公式.在K_2群方面,我们主要介绍了域上K_2群,代数整数环上K_2群以及著名的Birch-Tate猜想.并且也给出了K_2群一些计算方面的结果.
in this paper we consider lower K一groups: K_0,K_1 and K_2,and discusssome results of their latest development related to Bass一Quillen conjecture and Birch-Tate conjecture. For K_0 and K_1, from the implication of B-Q conjecture we can ex一plain the function of K_0 and K_1, and give over a polynomialring some computationalformula of automorphism groups of projective modules.As for K_2, we provide anintroduction to the K_2 groups of fields, the K_2 groups of the rings of algebraic in-tegers and the well-known B-T conjecture,We also give some results on computationof K_2 groups.
