A dilemma in representing observables in quantum mechanics

Quantum Physics 2010-10-19 v1

Abstract

There are self-adjoint operators which determine both spectral and semispectral measures. These measures have very different commutativity and covariance properties. This fact poses a serious question on the physical meaning of such a self-adjoint operator and its associated operator measures.
