* On the degeneration of the noncommutative Hodge-to-de Rham spectral sequence *

Some unfinished notes containing an exposition of parts of Kaledin's proof.
* 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.
