group\({\mathop {\mathbb H}\nolimits}^ d\) for the linear Schrödinger and wave equations
involving the sublaplacian. The Schrödinger equation on\({\mathop {\mathbb H}\nolimits}^
d\) is an example of a totally non-dispersive evolution equation: for this reason the classical
approach that permits to obtain Strichartz estimates from dispersive estimates is not
available. Our approach, inspired by the Fourier transform restriction method initiated in …
