The fundamental solution of a class of ultra-hyperbolic operators on Pseudo $H$-type groups

Wolfram Bauer, André Froehly, Irina Markina

Pseudo $H$-type Lie groups $G_{r,s}$ of signature $(r,s)$ are defined via a module action of the Clifford algebra $C{\ell }_{r,s}$ on a vector space $V\cong {\mathbb{R}}^{2n}$. They fo…
