SpletQuestion: 23. We know that the determinant of a matrix is invariant under a unitary change of basis (a) Show that the determinant of a Hermitian or unitary matrix Ω is therefore the product of its eigenvalues, that is b) As the trace of a matrix is also invariant under a unitary transfor- mation, show that the trace is the sum of the eigenvalues: 24. http://math.stanford.edu/~akshay/math113/hw6.pdf SpletWe have already chosen an orthonormal basis; and hence the bottom right corner takes on the form below: 2 4 1 0 0 0 cos(µ) ¡sin(µ) 0 sin(µ) cos(µ) 3 5 (see 4.5.2).

SpletAs you've said, change of basis doesn't change the linear transformation represented. Determinant is a geometric notion, it measures the change in volume after this linear transformation is applied. As such, it's invariant under change of basis. Trace is the derivative of determinant in some sense. It's the linearized version. SpletThe determinant, trace, eigenvectors, and eigenvalues of a linear endomorphism are invariant under a change of basis. In other words, the spectrum of a matrix is invariant …
