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 $C ℓ_{r, s}$ on a vector space $V ≅ R^{2 n}$ . They fo…

A co-dimensional 3 sub-Riemannian structure on Gromoll-Meyer exotic sphere

Wolfram Bauer, Kenro Furutani, Chisato Iwasaki

We construct a co-dimension $3$ completely non-holonomic sub-bundle on the Gromoll-Meyer exotic $7$ sphere based on its realization as a base space of a Sp(2)-principal bundle with…
