Matthieu Rosenfeld


I am currently a postdoc researcher at the University of Liège, working with the group of discrete mathematics. My research interests are combinatorics and theoretical computer science.

In 2017-2018 I was a postdoc at LIMOS.

I did my PhD thesis under the direction of Michaël Rao at the LIP. I worked on the avoidability of substructures in words. In particular, I studied the avoidability of patterns and powers in the usual, the abelian or the additive sens.

One example of such a result is: There exists an infinite sequence over a finite subset of ℤ2 that does not contain two consecutive factors of same size and same sum. It is still open whether it is also true over a finite subset of ℤ or not.
