Memoirs
Other mathematical texts
 Serre duality and geometric morphisms (2019), 4 pages. This unpublished note smoothes some wrinkles left unironed in article nr. 13 above.
 Categories and C*algebras: A commented (very partial) bibliography (2012), 4 pages. Once upon a time, I was asked about the use of category theory in connection with C*algebras, and this was my answer.
 A functorial equivariant Ktheory spectrum and an equivariant Lefschetz formula, with H. Emerson, T. Kandelaki and R. Meyer (2011), 20 pages. This work is an old preprint which has been superseded by item 11 above and thus will not be submitted for publication. Still, it is occasionally cited for the construction of the functorial equivariant Kheory spectrum for C*algebras, which didn't make it into the published article.
 Categories of C*algebras (2009), 9 pages. A rather pedantic writeup of the category theory needed to express Gelfand duality precisely.
 A survey of tensor triangular geometry and applications (2009), 6 pages. Extended abstract of lectures given in Oberwolfach on Paul Balmer's tensor triangular geometry.
 Biproducts in triangulated categories (2009), 2 pages. I've once written up the exercise that the existence of direct sums follows from the other axioms of a triangulated category.
