As he says it further: “These assumptions are reasonable on account of the eigenvalues of real linear operators being always real numbers”. Smooth Quantum Mechanics Quantum Mechanics without discontinuities in time evolution. Desai: “Quantum Theory is a linear theory …” We can discuss SHM We want the framework of Hilbert space, linear operators and all the rest to make our life easier. In order to clarify this correspondence, we need to study some properties of linear operators acting between tensor products of vector spaces. Quantum mechanics is the theory of that part of physics that can be understood in terms of linear operators on a Hilbert space called observables. Quantum mechanics (QM – also known as quantum physics quantum theory is a branch of physics dealing with physical phenomena at microscopic scales, where the action is on the order of the Planck constant. Special types of linear operators (Hermitian, unitary, inverse) and their properties. And momentum were no longer considered as values of functions on phase space, but as eigenvalues; more precisely: as spectral values (point spectrum plus absolute continuous plus singular continuous spectrum) of linear operators in Hilbert space. \item (d) Quantum mechanics is hard. I am planning on writing up a series of notes from the out of print book A Quantum Mechanics The other thing to note is that not every Hermitian operator is “closed”; that is it is possible for \psi to be square integrable but for operator H(\phi) = x \phi to not be square integrable. The spectral theory of linear operators plays a key role in the mathematical formulation of quantum theory. This question is hotly debated by people working in quantum optics, quantum computation and wherever foundations of quantum mechanics may enter. The projections on the observable's eigenspaces can be obtained by delayed initial conditions, imposed to the smooth time ..

Of course, this problem today appears far from being settled and is a heavy burden left us by . Furthermore, such a rigorous mathematical foundation leads to a more profound insight into the nature of quantum mechanics. Abstract I show that the apparent wave function collapse can take place smoothly, without discontinuities.
