Surgery and positive Bakry-Émery Ricci curvature
Philipp Reiser, Francesca Tripaldi
We consider the problem of preserving weighted Riemannian metrics of positive Bakry-Émery Ricci curvature along surgery. We establish two theorems of this type: One for connected s…
Multicomplexes on Carnot groups and their associated spectral sequence
Antonio Lerario, Francesca Tripaldi
The aim of this paper is to give a thorough insight into the relationship between the Rumin complex on Carnot groups and the spectral sequence obtained from the filtration on forms…
Extending an example by Colding and Minicozzi
Lorenzo Ruffoni, Francesca Tripaldi
Extending an example by Colding and Minicozzi, we construct a sequence of properly embedded minimal disks in an infinite Euclidean cylinder around the -axis with curvatu…
On the topology of surfaces with the generalised simple lift property
Francesca Tripaldi
In this paper, we study the geometry of surfaces with the generalised simple lift property. This work generalises previous results by Bernstein and Tinaglia, and it is motivated by…
