On Lp-improving for averages associated to mixed homogeneous polynomial hypersurfaces in ℝ3
We establish Lp-Lq estimates for averaging operators associated to mixed homogeneous polynomial hypersurfaces in ℝ3. These are described in terms of the mixed homogeneity and the order of vanishing of the polynomial hypersurface and its Gaussian curvature transversally to their zero sets.
