Woit · §5.2 Lie algebras of the orthogonal and unitary groups
英文原文
The author relates Ωᵀ = Ω⁻¹ to Xᵀ = −X and describes the resulting real matrices in so(n); the location is explanatory rather than a separately labelled definition.
原文相关讨论摘录
These give a path connecting to the identity (taking ). We saw above that the condition corresponds to skew-symmetry of the matrix
So in the case of , we see that the Lie algebra is the space of skew-symmetric by real matrices, together with the bilinear, antisymmetric product given by the commutator:

这些给出了一条连接 与恒等元的路径(取 )。我们在上面看到,条件 对应于矩阵 的反对称性。
因此在 的情形中,我们看到李代数 是斜对称 的 乘 实矩阵构成的空间,并带有由对易子给出的双线性、反对称乘积:
