Abstract: Abstract Most operators occurring in applications, like differential operators or multiplication operators, are unbounded. Quantum physics requires that such operators should act on some Hilbert spaces, so that one can talk about self-adjointness which is needed to give expectation values that are real numbers; such values are supposed to be the outcome of a measurement.
