Felix Cherubini's Research Page

Hi, I am Felix Cherubini (birth name: Felix Wellen) and this is my research website.

What my Research is About

I am interested in application of Homotopy Type Theory (HoTT) to Differential and Algebraic Geometry and, more generally, I want to know how well HoTT can help to make current research in pure mathematics more understandable. The synthetic algebraic geometry project I am currently working on, can be viewed here.

In early 2018, I wrote an essay describing my thesis for the German competition "Klartext!". It didn't win and it is in German, you can view it here.



Articles and Abstracts


Here is an overview of video recordings of talks about my topics:

This one might be the best place to start, if you want to understand the general direction of what I am interested in.

This one focuses on the cartan geometry from my thesis.

Those were tutorials 2 and 6, here is the complete list:

Tutorial 1 Dan Licata: A Fibrational Framework for Modal Simple Type Theories

Tutorial 2 Felix Wellen: The Shape Modality in Real cohesive HoTT and Covering Spaces

Tutorial 3 Dan Licata: Discrete and Codiscrete Modalities in Cohesive HoTT

Tutorial 4 Felix Wellen: Discrete and Codiscrete Modalities in Cohesive HoTT, II

Tutorial 5 Dan Licata: A Fibrational Framework for Modal Dependent Type Theories

Tutorial 6 Felix Wellen: Differential Cohesive HoTT
