AbstractWe prove Gevrey regularity for a class of operators defined on the torus Tm+n, with real analytic coefficients in Tm, and which are globally C∞ hypoelliptic. Then, we apply this result to show global Gs hypoellipticity for a large class of sublaplacians that may include lower order terms
We consider non-linear operators constructed from rigid vector fields. In particular, we study (glob...
