Curvature of an exotic 7-sphere
David S. Berman, Martin Cederwall, Tancredi Schettini Gherardini
We study the geometry of the Gromoll-Meyer sphere, one of Milnor's exotic -spheres. We focus on a Kaluza-Klein Ansatz, with a round as base space, unit as fibre, and…

Teleparallel Geroch geometry
Guillaume Bossard, Martin Cederwall, Jakob Palmkvist
We construct the teleparallel dynamics for extended geometry where the structure algebra is (an extension of) an untwisted affine Kac-Moody algebra. This provides a geometrisation…
