Galois cohomology and profinitely solitary Chevalley groups
Holger Kammeyer, Ryan Spitler
For every number field and every Cartan Killing type, there is an associated split simple algebraic group. We examine whether the corresponding…
Yamabe problem in the presence of singular Riemannian Foliations
Diego Corro, Juan Carlos Fernández and Raquel Perales
Using variational methods together with symmetries given by singular Riemannian foliations with positive dimensional leaves, we prove the existence of…
Stability of Einstein metrics and effective hyperbolization in large Hempel distance
Ursula Hamenstädt, Frieder Jäckel
Extending earlier work of Tian, we show that if a manifold admits a metric that is almost hyperbolic in a suitable sense, then there exists an…
Gromov-Hausdorff Limits of Closed Surfaces
Tobias Zisgen
We describe the Gromov-Hausdorff closure of the class of length spaces being homeomorphic to a fixed closed surface.
