    Is P^2 a projector operator, and what are its eigenvalues and eigenfunctions?

    Thank you Compuchip! I am asking about P. Yes, I know that P^2|x> = |x> which is not equal to p|x>. So it is not projection operator. My next confusion is can I write |-x> = -|x> ? How can we calculate the eigen value and eigen function of P
