# Maarten Derickx

## About meI'm Maarten Derickx. I'm currently an Algant PhD student at the universities of Leiden, Bordeaux and Milano.E-mail (university): mderickx@math.leidenuniv.nl E-mail (personal): maarten@mderickx.nl PhD Supervisors: Bas Edixhoven (Leiden), Pierre Parent (Bordeaux) and Bert van Geemen (Milano) |

## Projects

I help with the developement of Sage and I have my own sage server. If you want an account and I know you, then ask!I also keep a list of mathematical problems to wich I don't know the solution. If you can answer one of these you would make me very happy. Note that some (but probably not all) of these are open problems.

## Teaching (as assistant)

Algebra 2 (fall 201)Algebraic Geometry (spring 2012)

LAPP-Top, a special course for talented high school students (spring 2012)
