If A and B are Hermitian operators, prove that <A2>⩾0. Hermitian Operator: An adjoint of itself is a Hermitian operator. The Hermitian operator produces actual eigenvalues when applied to a quantum state. The eigenvalues are known as energy eigenvalues when the Hamilto...

Prove that the characteristic roots of a Hermitian matrix are real. What is the z component of r = a b + c, if a = 3.5 + 8.4 - 4.2, b = -1.8 + 1.5 + 7.7, and c = 6.1 + 4.4 + 2.4? Prove the following rule is true or false using...
For a norm v on I?, the complex n-tuples, an (n x n) matrix h is called norm-Hermitian if the numerical range of h with respect to v is real. (For a precise definition see Section 1 and the beginning of Section 3.) An unso...

In summary: B) + dim (nul B^T) = nMy bad, I was thinking of the matrix as a linear transformation and not as a matrix. It's been a while since I've done this stuff. So, if B is not invertible, then it's not surjective, and since it's not surjective it's not injective....
