摘要
本文研究了两个代数张量积的Ｇｒｏｔｈｅｎｄｉｅｃｋ群和Ｗｈｉｔｅｈｅａｄ群首先构作三个群同态，并证明：若Ｒ为增广Ａ－代数，则存在的子群Ｃ使得，并存在的子群Ｄ使得．然后给出在群代数和包络代数方面的应用，最后考虑的增广代数的情形．
In this paper we consider the Grothendieck group and the Whitehead group . We prove that if R is an argmented A -algebra then there exists a subgroup C of such that, and a subgroup D of such that.Some application for group algebras and enveloping algebras are given.
