本文主要研究有限维柔性合成代数的统一方法,包括其分类问题。复合代数是指特征为2的域F上的非结合代数A,它具有非退化对称双线性型(,),对所有x,y ∈ A都允许复合,其中x. y表示A中的乘法。如果A有一个单位元素,则称之为unital。根据著名的广义Hurwitz定理,F上的任何单位复合代数都有1,2,4或8维,
The primary concern in this paper is to present a unifying approach to the study of finite-dimensional flexible composition algebras, including its classification problem. By a composition algebra we mean a nonassociative algebra A over a field F of characteristic# 2 with a nondegenerate'symmetric bilinear form (,) permitting composition for all x, y E A, where x. y denotes the multiplication in A. If A has a unit element, then it is called unital. By the well-known generalized Hurwitz theorem, any unital composition algebra over F has dimension 1, 2, 4 or 8 and
