Risch Algorithmsubproblems, such as finding out if a given combination of elementary functions vanishes. But in practice computer algebra systems are quite good in solving such problems. Here we shall consider, at a very elementary level, the main ideas of the Risch algorithm; see [16] for more details.

Quantum Oscillator a scale of length ., momentum ., energy ., and any other quantity of any dimensionality. They have the meaning of the characteristic amplitude, momentum, and energy of zero oscillations. We shall put ., . = 1, and . = 1, thus choosing these characteristic scales as units for measurement of corresponding quantities.
