We study those pre-Hilbert absolute-valued algebras satisfying the identity . We prove that such an algebra is finite-dimensional in each one of the following two cases:
- (1)
satisfies the additional identity ,
- (2)
contains a weak left-unit.
In the first case is flexible and isomorphic to either , , , , , , or . In the second one has a left-unit and is isomorphic to either , , , , , , or . We also prove the existence of infinite-dimensional pre-Hilbert absolute-valued algebras satisfying and containing only a non-zero idempotent.

在满足 ( x 2 , y , x 2 )=0 的绝对值代数上
我们研究那些满足恒等式的前希尔伯特绝对值代数 . 我们证明这样的代数 在以下两种情况中的每一种情况下都是有限维的:
- (1)
满足附加身份 ,
- (2)
包含一个弱左单元。
在第一种情况下 是灵活的和同构的 , , , , , , 或者 . 在第二个 有一个左单位并且同构于 , , , , , , 或者 . 我们还证明了无限维前希尔伯特绝对值代数的存在满足 并且只包含一个非零幂等项。
