An complex matrix A is Hermitian(or self-adjoint) if A∗ = A. Note that a Hermitian matrix is automatically square. For real matrices, A∗ = AT, and the deﬁnition above is just the deﬁnition of a symmetric matrix. Example. Here are examples of Hermitian matrices: −4 2+3i 2−3i 17 , 5 6i 2 −6i 0.87 1−5i 2 1+5i 42 .

Suppose H is a complex Hilbert space, with inner product . 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 the continuous linear operator A : H → H satisfying Existence and uniqueness of this operator follows from the Riesz representation theorem. This can be seen as a generalization of the adjoint matrix of a square matrix which has a simila…
