my name is Stephan Alexander Spahn. I study mathematics at the Karlsruhe Institute of Technology, where my main interests are category theory, logic and algebraic geometry. Further interests of mine are philosophy, music, visual arts and most things, which are involved in any kind of lnguage or symbolic encoding. I use wikimedia objects since 2008 and created my current account in 2010. I speak german, english, french and chinese (in order of decreasing abilities).
