我们证明任何维数⩽5的实李群都承认左不变平面射影结构。我们还证明,当且仅当 L 的李代数不完美时,维度⩽5 的实李群 L 才承认左不变平面仿射结构。
We prove that any real Lie group of dimension ⩽5 admits a left invariant flat projective structure. We also prove that a real Lie group L of dimension ⩽5 admits a left invariant flat affine structure if and only if the Lie algebra of L is not perfect.
