In this note we study the Lp-Lq boundedness of Fourier multipliers of anharmonic oscillators, and as a consequence also of spectral multipliers, for the range 1 < p ≤ 2 ≤ q < ∞. The underlying Fourier analysis is associated with the eigenfunctions of an anharmonic oscillator in some family of differential operators having derivatives of any order. Our analysis relies on a version of the classical Paley-type inequality, introduced by Hörmander, that we extend in our nonharmonic setting.Dans cette note, nous étudions la Lp-Lq continuité des multiplicateurs de Fourier des oscillateurs anharmoniques, et par conséquent des multiplicateurs spectraux également, pour 1 < p ≤ 2 ≤ q < ∞. L’analyse de Fourier sous-jacente est associée aux fonctions pr...
