WebHermitian Operators •Definition: an operator is said to be Hermitian if it satisfies: A†=A –Alternatively called ‘self adjoint’ –In QM we will see that all observable properties must be represented by Hermitian operators •Theorem: all eigenvalues of a Hermitian operator are real –Proof: •Start from Eigenvalue Eq.: WebAn orthogonal matrix is a square matrix A if and only its transpose is as same as its inverse. i.e., A T = A-1, where A T is the transpose of A and A-1 is the inverse of A. From this definition, we can derive another definition of an orthogonal matrix. Let us see how. A T = A-1. Premultiply by A on both sides, AA T = AA-1,. We know that AA-1 = I, where I …
