  We propose quantization relationships which would let us describe and
solution problems originated by conflicting or cooperative behaviors among the
members of a system from the point of view of quantum mechanical interactions.
The quantum analogue of the replicator dynamics is the equation of evolution of
mixed states from quantum statistical mechanics. A system and all its members
will cooperate and rearrange its states to improve their present condition.
They strive to reach the best possible state for each of them which is also the
best possible state for the whole system. This led us to propose a quantum
equilibrium in which a system is stable only if it maximizes the welfare of the
collective above the welfare of the individual. If it is maximized the welfare
of the individual above the welfare of the collective the system gets unstable
and eventually it collapses.
