Strong Novikov conjecture for low degree cohomology and exotic group C*-algebras
P. Antonini, A. Buss, A. Engel, T. Siebenand
We strengthen a result of Hanke-Schick about the strong Novikov conjecture for low degree cohomology by showing that their non-vanishing result for...
Moduli space of metrics of nonnegative sectional or positive Ricci curvature on homotopy real projective spaces
Anand Dessai, David González-Álvaro
We show that the moduli space of metrics of nonnegative sectional curvature on every homotopy RP^5 has infinitely many path components. We also show...
Handlebody Bundles and Polytopes
Sebastian Hensel and Dawid Kielak
We construct examples of fibered three-manifolds with fibered faces all of whose monodromies extend to a handlebody.
A flow approach to Bartnik's static metric extension conjecture in axisymmetry
Carla Cederbaum, Oliver Rinne, Markus Strehlau
We investigate Bartnik's static metric extension conjecture under the additional assumption of axisymmetry of both the given Bartnik data and the...
