Mathematical interests

• finite groups

• characters and representations

• block theory

• permutation groups

• fusion systems

• finite-dimensional algebras

A good overview of my work is contained in the slides of my talk at the TU Munich. I wrote a number of expository papers, which indicate my favorite subjects:

• Pseudo Sylow numbers and pseudo Frobenius numbers

• Inverse problem for automorphism groups

• Orders of permutation groups

• Formal power series

• Fusion theorems in finite groups

• Complements in finite groups

Personal interests

• running (formerly: basketball, skateboarding, juggling, gymnastics, climbing, slacklining)

• piano (playing and recording, e.g. Rachmaninoff, Prelude op. 3-2, c-sharp minor; 20 years ago, I was also into composing, e.g. Etude)

• water color painting (e.g. Mushrooms)

• nature (lowering CO₂ footprint, fight global warming)

• arch linux, LaTeX, programming

• psychology

• creative writing

• sugarfree sustainable food

My personal bests in running are:

• 1.000m in 2:58min

• 3.000m in 9:53min

• 5.000m in 16:58min

• 10.000m in 35:22min

(all with spikes on track).
