Positive scalar curvature and low-degree group homology
Noé Bárcenas, Rudolf Zeidler
Let be a discrete group. Assuming rational injectivity of the Baum-Connes assembly map, we provide new lower bounds on the rank of the positive scalar curvature bordism group a…

Analytical Signatures and Proper Actions
Noé Bárcenas, Quitzeh Morales Meléndez
In this short note we compare Mishchenko's definition of noncommutative signature for a manifold with proper -action of a discrete, countable group with the (more analytical…

Multiplicative Structures and the Twisted Baum-Connes Assembly map
Noé Bárcenas, Paulo Carrillo Rouse, Mario Velásquez
Using a combination of Atiyah-Segal ideas on one side and of Connes and Baum-Connes ideas on the other, we prove that the Twisted geometric K-homology groups of a Lie groupoid have…
