L^p(R^n)-continuity of translation invariant anisotropic pseudodifferential operators: a necessary condition

S. Coriasco, M. Murdocca

We consider certain anisotropic translation invariant pseudodifferential operators, belonging to a class denoted by $\mathrm{op}({\mathcal{M}}_{\psi }^{\lambda })$, where $\lambda$ and $ψ=(ψ_1,\dots,ψ_n)…
