    "abstract": "We discuss the relationship between exact solvability of the Schroedinger\nequation, due to a spatially dependent mass, and the ordering ambiguity. Some\nexamples show that, even in this case, one can find exact solutions.\nFurthermore, it is demonstrated that operators with linear dependence on the\nmomentum are nonambiguous.",
