Consider two observers and related by a symmetry transformation such as a translation , or rotation where , etc. For any state corresponding to a ray according to let assign the ray , and for any observable assigned the self-adjoint operator by let assign the operator . Since the physical elements are determined by the modulus squared of the matrix elements between states (being the probability of transition between states) and the expectation values of observables, this correspondence is said to be a symmetry transformation if
