A multiplier theorem for sub-Laplacians with drift on Lie groups

Alessio Martini, Alessandro Ottazzi, Maria Vallarino

We prove a general multiplier theorem for symmetric left-invariant sub-Laplacians with drift on non-compact Lie groups. This considerably improves and extends a result by Hebisch,…

From refined estimates for spherical harmonics to a sharp multiplier theorem on the Grushin sphere

Valentina Casarino, Paolo Ciatti, Alessio Martini

We prove a sharp multiplier theorem of Mihlin-Hörmander type for the Grushin operator on the unit sphere in , and a corresponding boundedness result for the associate…
