The classical-statistical limit of quantum mechanics is studied. It is proved that the limit ~ → 0 is the good limit for the operators algebra but it si not so for the state compact set. In the last case decoherence must be invoked to obtain the classical-statistical limit.

The major goal of the current research is to present conception “(bi)*-neutrosophic soft limit points” in “neutrosophic Bitopological” spaces. In addition, aims give essential theorems related topic with illustrative examples
