Geodesic inversion and Sobolev spaces on Heisenberg type groupsArkiv för Matematik - Tập 43 - Trang 51-67 - 2005
Francesca Astengo, Bianca Di Blasio
Let σ be the geodesic inversion on a Heisenberg type groupN with homogeneous dimensionQ, and denote byS the jacobian of σ. We prove that, for
$$ - \frac{1}{2}Q< \alpha< \frac{1}{2}Q$$
, the operators
$$T_\alpha :f \mapsto S^{1...... hiện toàn bộ
