Query: An axiomatic formulation of the Montevideo interpretation of quantum
  mechanics   We make a first attempt to axiomatically formulate the Montevideo
interpretation of quantum mechanics. In this interpretation environmental
decoherence is supplemented with loss of coherence due to the use of realistic
clocks to measure time to solve the measurement problem. The resulting
formulation is framed entirely in terms of quantum objects without having to
invoke the existence of measurable classical quantities like the time in
ordinary quantum mechanics. The formulation eliminates any privileged role to
the measurement process giving an objective definition of when an event occurs
in a system.
