$L^\infty$-$BMO$ bounds for pseudo-multipliers associated to the harmonic oscillator

Abstract

In this note we investigate some conditions of H\"ormander-Mihlin type in order to assure the $L^\infty$-${\textnormal{BMO}}$ boundedness for pseudo-multipliers of the harmonic oscillator. The $\textnormal{H}^1$-$L^1$ continuity for Hermite multipliers also is investigated. The final version of this paper will appear in Rev. Colombiana Mat.
