My name is Axel Boldt and I teach mathematics at Metropolitan State University in Saint Paul, Minnesota. In addition to mathematics, I'm interested in molecular biology,
theoretical computer science, physics, astronomy, free software, (political) philosophy, chess, and many other things. My home page is at math-www.uni-paderborn.de/~axel/.
Since I believe that "intellectual property rights" do not exist (as we mere mortals cannot arrogate the right to own parts of Plato's eternal heaven of ideas), every word I write is by default, and always, in the public domain.
