Definition | df-adjh 31877* | Define the adjoint of a Hilbert space operator (if it exists). The domain of adjℎ is the set of all adjoint operators. Definition of adjoint in [Kalmbach2] p. 8. Unlike Kalmbach (and most authors), we do not demand that the operator be linear, but instead show (in adjbdln 32111) that the adjoint exists for a bounded linear operator.

Definition | df-bra 31878* |
Define the bra of a vector used by Dirac notation. Based on definition
of bra in [Prugovecki] p. 186 (p.
180 in 1971 edition). In Dirac
bra-ket notation, 〈𝐴 ∣ 𝐵〉 is a complex number equal to
the inner
product (𝐵 ·ih 𝐴). But physicists like
to talk about the
individual components 〈𝐴 ∣ and ∣
𝐵〉, called bra
and ket
respectively. In order for their properties to make sense formally, we
define the ket ∣ 𝐵〉 as the vector 𝐵 itself,
and the bra
〈𝐴 ∣ as a functional from ℋ to ℂ. We represent the
Dirac notation 〈𝐴 ∣ 𝐵〉 by ((bra‘𝐴)‘𝐵); see
braval 31972. The reversal of the inner product
arguments not only makes
the bra-ket behavior consistent with physics literature (see comments
under ax-his3 31112) but is also required in order for the
associative law
kbass2 32145 to work.
Our definition of bra and the associated outer product df-kb 31879 differs from, but is equivalent to, a common approach in the literature that makes use of mappings to a dual space. Our approach eliminates the need to have a parallel development of this dual space and instead keeps everything in Hilbert space. For an extensive discussion about how our notation maps to the bra-ket notation in physics textbooks, see mmnotes.txt 31879, under the 17-May-2006 entry. (Contributed by NM, 15-May-2006.)

Definition | df-kb 31879* | Define a commuted bra and ket juxtaposition used by Dirac notation. In Dirac notation, ∣ 𝐴〉〈𝐵 ∣ is an operator known as the outer product of 𝐴 and 𝐵, which we represent by (𝐴 ketbra 𝐵). Based on Equation 8.1 of [Prugovecki] p. 376. This definition, combined with Definition df-bra 31878, allows any legal juxtaposition of bras and kets to make sense formally and also to obey the associative law when mapped back to Dirac notation.
