  The standard formulation of Quantum Mechanics violates locality of
interactions and the action reaction principle. An alternative formulation in
an extended phase space could preserve both principles, but Bell's theorems
show that a distribution of probability in a space of local variables can not
reproduce the quantum correlations.
  An extended phase space is defined in an alternative formulation of Quantum
Mechanics. Quantum states are represented by a complex va\-lued distribution of
amplitude, so that Bell's theorems do not apply.
