WebMar 6, 2024 · First off, a projector P is said to be an operator that squares to itself, P2 = P. With that, its eigenvalue is either 0 or 1. Are these properties, P2 = P and Eigenvalues(P) = {1, 0}, only true in a certain representation? Edit: The answer to the above question is no and that indeed those properties hold for both of the representations.
