I am currently a PhD student under the supervision of Alessandro Ardizzoni (UniTo) and Leandro Vendramin (VUB). I work with the Research group in Algebra and Algebraic Geometry in Torino, and I am a member of the VUB Algebra Research Group in Brussel.

The extended abstract of my talk in the Oberwolfach Mini-Workshop The Yang–Baxter Equation and Representations of Braid Groups will be available soon

Ferri, D., Split Lemma and First Isomorphism Theorem for groupoids. arXiv preprint arxiv:2509.13973 (2025).

This is a preliminary version, to be expanded. Any comments (including suggested references) are welcome!

Update: Thanks for the suggestions already received! A new expanded version will appear in the next months.
