what I’ve been doing lately

Geometry of surfaces and its relations with number theory here are some preprints.

Introduction à la programmation

Evaluation is by project. Here are some of the finished projects from 2020 and 2021:

  1. sudoko with digit recognition
  2. labrinths on surfaces
  3. labrinths classic
  4. Mastermind d’apres Knuth

Video of a 120-cell by Muaad Tamtam et Damis El Alami.

And this is something I learned to do by talking to the students (and going on forums).

Simulation of an epidemic

I embedded this in a script with pygame too


What (else) do I do?

seminars I go to

Basically if you are looking for me on a Thursday well….forget it!

and a little more…

I am a (low dimensional) topologist a subject which has it’s origins in the work of the French mathematician Henri Poincaré. Recently I have been doing a lot of

I was a member of ICERM at Brown University in 2019 participating in Illustrating Math and visits to

Here is the book that we wrote during the semester.

And where I got time to do write stuff forInkscape like this Apollonian Packings


This is what I look like

Themes

This is a quasi-Fuchsian manifold: it’s a basic kind of 3 manifold homeomorphic to the product of a surface and an interval together with a (non unique) choice of hyperbolic metric. Togther with Prof. S. Kojima of TITEC we are working on applying converegence results for quasi-Fuchsian manifolds and Teichmueller theory to get information about closed hyperbolic manifolds.

With Bill Goldman and a couple of his ex students we have been working on a book that just got published by the AMS. Much of it is dedicated to explaining this picture of an invariant fractal in the character variety.

Recent preprints

Mostly geometry of surfaces and (elementary) number theory.

stages

From March 2014 I’ve also been working with the fablab MSTIC making mathematical curiosities from wood. I’m mainly interested in constructing geometric objects in wood using kerf bending patterns. Wood prepared using a laser cutting machine can be bent and joined to like a 3 dimensional jigsaw puzzle. collection of pieces

In November 2014 I was invited to take part in a workshop forarchitectural students Architect 2.0 Grenoble to explain the techniques and possibilities.
