A is an operator and Uinv is the inverse of operator U(adsbygoogle = window.adsbygoogle || []).push({});

How am I to show that A and Uinv(A)U have the same eigenvalues? Must U be unitary for this to be true?

And if the eigenvectors of A are (Psi n), what are the eigenvectors of Uinv(A)U?

Help anyone? Not sure what to do here.
