Peter Woit: Quantum Mechanics for Mathematicians Let us denote {widehat{R}|psi(mathbf{z}) with {widehat{R}} the operator of an elementary time-reversal transformation. Roughly speaking, Fourier integral operators are to linear PDE as canonical transformations are to Hamiltonian mechanics (and one can in fact view FIOs as a quantisation of a canonical transformation). In more technical terms, calculations in quantum mechanics make use of Hilbert spaces, vector, linear operators, inner products, dual spaces, and Hermitian conjugation. Anti-linear transformations appear in quantum mechanics exclusively for time-reversal transformations. During the same period, Hungarian polymath John von Neumann formulated the rigorous mathematical basis for quantum mechanics as the theory of linear operators on Hilbert spaces, as described in his likewise famous 1932 textbook. 1.2 Basic The observables of a quantum mechanical system are given by self-adjoint linear operators on H…. There's a theorem that asserts uncertainty is only obeyed by linear operators (like the linear operators of quantum mechanics). That captures the distribution of functions in both space and frequency, albeit with some “quantum fuzziness” that shows up whenever one tries to inspect this measure at scales of physical space and frequency space that together violate the uncertainty principle. It was developed in parallel with a new approach to the mathematical spectral theory based on linear operators rather than the quadratic forms that were David Hilbert's approach a generation earlier. Theory of Linear Operators in Hilbert Space (Dover Books on. 237: Linear Operators for Quantum Mechanics - Google Books Topics include linear spaces, functionals, and operators;.
