    (Nearly) sample-optimal sparse fourier transform by Indyk, Piotr, Kapralov, Mikhail, Price, Eric C

    Published 2018
    “…We consider the problem of computing a k-sparse approximation to the discrete Fourier transform of an n-dimensional signal. Our main result is a randomized algorithm that computes such an approximation using O(k log n(log log n)[superscript O(1)]) signal samples in time O(k log[superscript 2] n(log log n)[superscript O(1)]), assuming that the entries of the signal are polynomially bounded. …”

    FOURIER-TRANSFORM METHOD FOR THE CLASSICAL TRAJECTORY PROBLEM by Nesbet, R, Clary, D

    Published 1979
    “…Recent theoretical developments in classical bound-state dynamics, which make use of the geometrical structure in phase space known as an invariant toroid, can then be applied to collision problems. Fast Fourier transform techniques are used to construct the invariant toroid, which is the locus of an indefinitely extended nonperiodic classical trajectory. …”
