About
Danish amateur mathematician in the sense that I don't hold an academic position. I have a long interest in elliptic curves since my university studies.
I wrote my master's thesis on modular symbols and the work of John Cremona 25 years ago, and have been doing my own research on these subjects throughout the years.
