设R是一个具有单位元gl(n,R)的任意交换环由R上所有n×n矩阵组成的一般线性李代数,n (n,R)由所有严格上三角矩阵组成的gl(n,R)的子代数。本文给出了N(N,R)的任意导数的显式描述。
Let R be an arbitrary commutative ring with identity, gl(n,R) the general linear Lie algebra consisting of all n×n matrices over R, N(n,R) the subalgebra of gl(n,R) consisting of all strictly upper triangular ones. In this paper, we give an explicit description of any derivations of N(n,R).
