quantum mechanics - Why path integral approach may suffer from operator ordering problem?


In Assa Auerbach's book (Ref. 1), he gave an argument saying that in the normal process of path integral, we lose information about ordering of operators by ignoring the discontinuous path.


What did he want to say? I don't think there is any problem related to the ordering of operators.

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
