WebbAn Hermitian operator is the physicist's version of an object that mathematicians call a self-adjoint operator. It is a linear operator on a vector space V that is equipped with positive definite inner product. In physics an inner product is usually notated as a bra and ket, following Dirac. Thus, the inner product of Φ and Ψ is written as, Webb26 sep. 2024 · that is, [ A, B] is skew-hermitian; thus if we set (4) i C † = − [ A, B] † = [ A, B], then i C † is also skew. We now observe that an operator D is skew if and only if i D is …

III goes into inner products, Hermitian, anti-Hermitian, and unitary operators, and we find that we do not need to speak of the adjoint of an operator nor of a dual vector space.
