Who am I?I am a mathematician under an APART fellowship of the Austrian Academy of Sciences.My research interests include Ramsey theory, model theory, universal algebra, theoretical computer science. In this very moment, I am probably at one of the following institutions:
These are my ancestors. Non-mathematicians who came here by accident are obliged to read all of the following texts on what I am doing.
