Woit · §5.2 Lie algebras of the orthogonal and unitary groups
英文原文
The author names the skew-adjoint condition X† = −X and states that it is sufficient for exponentiation into the group; the section later identifies the same class as skew-Hermitian.
原文相关讨论摘录
so the matrices we want to exponentiate must be skew-adjoint (it can be shown that this is also a sufficient condition), satisfying
