标题[五行] 末学觉得exp人很纯真自然
时间Sun Jan 6 05:36:29 2013
所以末学试着证明了一下:
Let v∈G_e,
and let θ: R^1 → G be the corresponding 1-parameter subgroup of G.
Then φθ: R^1 → H is the 1-parameter subgroup of H corresponding to φ'v.
Thus, exp(φ'v) = φθ(1) = φexp(v).
The following diagram is commutative:
φ'
G_e ───→ H_e
| |
exp| |exp
| |
↓ ↓
G ───→ H
φ
i.e. exp is natrual.
