The inner product on Hilbert space ( , ) (with the first argument anti linear as preferred by physicists) is fully equivalent to an (anti-linear) identification between the space of kets and that of bras in the bra ket notation: for a vector ket = | define a functional (i.e. bra) = | by
ket (for a ket vector), bra-ket (for the inner product), or; Symbol 1: if 1 is set to bra or ket: enter the first symbol for the bra or ket, if 1 is set to bra-ket: enter the symbol for the bra part of the inner product; Symbol 2: if 1 is set to bra or ket: this parameter is not needed.

In mathematics, an inner product space (or, rarely, a Hausdorff pre-Hilbert space [1] [2]) is a real vector space or a complex vector space with an operation called an inner product. The inner product of two vectors in the space is a scalar, often denoted with angle brackets such as in , .
The inner product of two vectors is commonly written as ... In quantum mechanics, angle brackets are also used as part of Dirac's formalism, bra–ket notation, ...

In mathematical physics, especially quantum mechanics, it is common to write the inner product between elements as a|b , as a short version of a| · |b , or a| Ô |b , where Ô is an operator. This is known as Dirac notation or bra–ket notation, to note vectors from the dual spaces of the Bra A| and the Ket |B .
More specifically, the arrows encode angular momentum states in bra–ket notation and include the abstract nature of the state, such as tensor products and transformation rules. The notation parallels the idea of Penrose graphical notation and Feynman diagrams.
