Lower bounds for pseudo-differential operators

Nicolas Lerner, Jean Nourrigat (1990)

Annales de l'institut Fourier


This paper contains some new results on lower bounds for pseudo-differential operators whose symbols do not remain positive. Non-negativity of averages of the symbol on canonical images of the unit ball is sufficient to get a Gårding type inequality for Schrödinger operators with magnetic potential and one dimensional pseudo-differential operators.
