Abstract
We study the local regularity of the analytic/Gevrey vectors for the general class of Hörmander’s operators, meaning those of degenerate elliptic type or of degenerate parabolic type, thus improving the result obtained by M. Derridj in 2019 (Tunisian J Math 1(3):321–345, 2019). The optimal result in the degenerate elliptic case was obtained by the second author in 2019 (Pac J Math 302:511–543, 2019), and we obtain in this chapter optimal result in the degenerate parabolic case.| File | Dimensione | Formato | |
