Actually, you can view a bra vector as the honest-to-goodness adjoint of the corresponding ket vector, but it requires a trick. So, let V be a finite-dimensional complex inner product space. The trick is that you have a canonical isomorphism Φ: V → L ( C, V) given by Φ ( v): λ ↦ λ v for all v ∈ V; indeed, one has that Φ − 1 ( s ...
