Sub-Finsler geometry and finite propagation speed
Michael G. Cowling, Alessio Martini
We prove a number of results on the geometry associated to the solutions of evolution equations given by first-order differential operators on manifolds. In particular, we consider…

Weighted Plancherel estimates and sharp spectral multipliers for the Grushin operators
Alessio Martini, Adam Sikora
We study the Grushin operators acting on and defined by the formula \[ L=-\sum_{\jone=1}^{d_1}\partial_{x'_\jone}^2 - (\sum_{\jone=1}^{d_1}|x'_\…

Algebras of differential operators on Lie groups and spectral multipliers
Alessio Martini
This thesis is devoted to the study of joint spectral multipliers for a system of pairwise commuting, self-adjoint left-invariant differential operators L_1,...,L_n on a connected…
