WitrynaThe definition of the Hermitian Conjugate of an operator can be simply written in Bra-Ket notation. Starting from this definition, we can prove some simple things. Taking the … In mathematics, the conjugate transpose, also known as the Hermitian transpose, of an complex matrix is an matrix obtained by transposing and applying complex conjugate on each entry (the complex conjugate of being , for real numbers and ). It is often denoted as or or , and very commonly in physics as . For real matrices, the conjugate transpose is just the transpose, .

In mathematics, specifically in operator theory, each linear operator $${\displaystyle A}$$ on a Euclidean vector space defines a Hermitian adjoint (or adjoint) operator $${\displaystyle A^{*}}$$ on that space according to the rule $${\displaystyle \langle Ax,y\rangle =\langle x,A^{*}y\rangle ,}$$ Zobacz więcej Consider a linear map $${\displaystyle A:H_{1}\to H_{2}}$$ between Hilbert spaces. Without taking care of any details, the adjoint operator is the (in most cases uniquely defined) linear operator Zobacz więcej Suppose H is a complex Hilbert space, with inner product $${\displaystyle \langle \cdot ,\cdot \rangle }$$. Consider a continuous linear operator A : H → H (for linear operators, continuity is equivalent to being a bounded operator). Then the adjoint of A is … Zobacz więcej A bounded operator A : H → H is called Hermitian or self-adjoint if $${\displaystyle A=A^{*}}$$ which is … Zobacz więcej For an antilinear operator the definition of adjoint needs to be adjusted in order to compensate for the complex conjugation. An adjoint operator of the antilinear operator A on a complex Hilbert space H is an antilinear operator A : H → H with the property: Zobacz więcej Let $${\displaystyle \left(E,\ \cdot \ _{E}\right),\left(F,\ \cdot \ _{F}\right)}$$ be Banach spaces. Suppose $${\displaystyle A:D(A)\to F}$$ and $${\displaystyle D(A)\subset E}$$, … Zobacz więcej The following properties of the Hermitian adjoint of bounded operators are immediate: 1.
