Conformally Covariant Bi-Differential Operators on a Simple Real Jordan Algebra

Salem Ben Said, Jean-Louis Clerc, Khalid Koufany

For a simple real Jordan algebra $V,$ a family of bi-differential operators from ${\mathcal{C}}^{\infty }(V\times V)$ to ${\mathcal{C}}^{\infty }(V)$ is constructed. These operators are cova…
