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 $${\displaystyle \langle Ax,y\rangle =\langle x,A^{*}y\rangle ,}$$ Visualizza altro 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 Visualizza altro Suppose H is a complex Hilbert space, with inner product $${\displaystyle \langle \cdot ,\cdot \rangle }$$. Consider a continuous Visualizza altro Definition Let the inner product $${\displaystyle \langle \cdot ,\cdot \rangle }$$ be linear in the first argument.
