I am an editor of the Houston Journal of Mathematics. For submission requirements please refer to the Information for Authors.

 

 

I am Professor of Algebra at Radboud University and I gave my inaugural lecture on 12 March 2009. The text, on Duality, is here: Oratie

 

Mathematically and Computationally Relevant Dualities, NWO funded research project with Bart Jacobs, Sam van Gool, and Jorik Mandemaker.

Teaching:

Model Theory – Course to be taught spring 2010 in Mastermath.

Lattice Theory – Course to be taught fall 2009 at RU.

Universal Algebra – Course to be taught spring 2009 at RU.

 

Outreach:

For the Nijmeegse 2-daagse, fall 2009, Dion Coumans, Lorijn van Rooijen gave a course based on materials we made together.

In spring 2009, Dion Coumans, Marleen Kock, and I did a project on Sierpinski’s Triangle in two classes at Dominicus College. Here are a few pictures from one of the classes.
