The 3D index and Dehn filling
We provide a rigorous proof of the Gang-Yonekura formula describing the transformation of the 3D index under Dehn filling a cusp in an orientable 3-manifold. The 3D index, originally introduced by Dim...

Very excited that my paper "Discrete signature tensors for persistence landscapes" with @haharrington.bsky.social and Daniel Tolosa is now on arXiv! We use discrete signature tensors to vectorise barcodes, and we showcase such approach on a knotted protein dataset.

Discrete signature tensors for persistence landscapes
Signature tensors of paths are a versatile tool for data analysis and machine learning. Recently, they have been applied to persistent homology, by embedding barcodes into spaces of paths. Among the d...

Exciting to see this one out!!
Very happy that my work with @agnesebarbensi.bsky.social is finally preprinted. We developed a very cool technique to see how the topology of open curves evolves, and applied it to learn some cool things about knotted proteins.
