I hope everyone enjoyed their holidays. I am wishing you all the best for the new year to come. 

After the break, the complexity seminar is coming back with:

     **today at 2.30pm**, a talk by Christophe Tollu on the Mignon-Ressayre lower bounds for the determinantal complexity of the permanent. We will be meeting in hybrid mode as usual: in room B107 and on the dedicated BBB room https://bbb.lipn.univ-paris13.fr/b/sei-nlh-8vr-xvy.

The next talk is planned on Monday 16th January, at 2.30pm. We will welcome Bruno Escoffier who will give an introduction to optimisation problems. 

Best,
