I'm currently a university student in Germany. Don't really know what else to write here. I'm interested in all kinds of mathematical topics; the current focus of my interests is Real and Complex analysis, but I'm also open-minded to everything else and enjoy the feeling of understanding a complicated topic or having solved a tough problem.
