| Abstract: | Some aspects of the transition probability P( ,  ) between states , on unital *-algebras are discussed. It is shown that P increases under the action of any stochastic linear map T, i.e., P(T, T) P(, ). Some properties of P are derived in starting from a recently-proved characterization of the quantity in question. |
