8 The Heisenberg`s Uncertainty Principle
... From the right hand sides of the last two equations it follows that |χi is also an eigenvector of  with eigenvalue a. This could only happen if: (a) |χi = b |ηi since |ηi is an eigenvector of  with eigenvalue a. Hence commuting operators have simultaneous eigenstates. That is these can be exactl ...
