Spectral multiplier theorems of Euclidean type on new classes of 2-step stratified groups

Alessio Martini, Detlef Müller

From a theorem of Christ and Mauceri and Meda it follows that, for a homogeneous sublaplacian $L$ on a $2$-step stratified group $G$ with Lie algebra $\mathfrak{g}$, an operator of…
