Transpose of a matrix is obtained by interchanging rows and columns. Co-factor of each element is the determinant value,In mathematics, a Hermitian matrix (or self-adjoint matrix) is a complex square matrix that is equal to its own conjugate transpose—that is, the element in the i-th row and j-th column is equal to the complex conjugate of the element in the j-th row and i, The nilpotent block is also similar to its adjoint (you can just explicitly show that a matrix in Jordan normal form with 0 s on the diagonal is similar to its adjoint). Putting this together, you can conclude that A is similar to its adjoint. As a hint , @V.González That is the definition of a matrix representing a linear operator. A linear operator is determined by where it sends basis vectors - that the expression on the left hand side. The right hand side is witness to the fact that any vector can be ,For part (b), you are on the right track but you want to adopt a different approach. The question is about the eigenvalues of A ∗ A , not those of A . So suppose x is an eigenvector of A ∗ A , i.e. A ∗ A x = q x for some scalar q . Now you can use your ap,See self-adjoint operator for a detailed discussion. If the Hilbert space is finite-dimensional and an orthonormal basis has been chosen, then the operator A is self-adjoint if and only if the matrix describing A with respect to this basis is Hermitian, i,where the conjugate transpose is denoted A^(H) , A^(T) is the transpose, and z^_ is the complex conjugate. If a matrix is self-adjoint, it is said to be Hermitian. SEE ALSO: Adjoint, Hermitian Matrix, Transpose. CITE THIS AS: Weisstein, Eric W. "Self,Self-adjoint operator.
