- On the global rigidity of projective space
A note containing an elementary proof that projective space does not
admit any global deformations as a smooth projective variety.
- GAP for tau-tilting modules
GAP-code for various computations involving tau-tilting modules, which was used in this paper.
- Manin's universal Hopf algebras and highest weight categories
Slides for a general audience talk on my PhD thesis.
- Koszul algebras from Frobenius splitting
Notes (by Philipp Lampe) for my talk at the BIREP Summer School on Koszul Duality (August 2015).
- Rationality of couples of 3x3 matrices under simultaneous conjugation
An alternative elementary proof by Kevin De Laet and myself of a result originally established by Formanek in 1979. For matrices of arbitrary size this is one my favourite open problems!
- Preprojective algebras and Lusztig's nilpotent variety
Some old and unedited notes for my talk at the BIREP Summer School on Preprojective Algebras (August 2013). They contain a simple proof showing that Lusztig's nilpotent variety is Lagrangian.
- Here are some photos I took.
- Here is one of my all-time favourite movie scenes, from Down by Law by director Jim Jarmusch.
- Some impressions from Kyoto.
