I'm reading a paper and it says the following:
Let $K$ be a Lie group and fix an orthonormal framing $\{e_1, ..., e_n\}$ with respect to a left-invariant metric. This gives a splitting $$T^∗K = K × \mathbb R^n$$ which determines in an obvious way a hermitian almost complex structure and an invariant $(n, 0)$-form on teh cotangent bundle $T^*K$.
I see how we get the splitting of the cotangent bundle by taking the coframe, but I do not see how this immediately determines a hermitian almost complex structure and $(n,0)$-form.
Could someone point me in the right direction? Thanks.
