About me Publications and Talks Teaching CV Other PhD Defense

OK, my PhD defense is over, but I leave this here for nostalgia!

When? The 21st of March at 9:30. Be on time!!

Where? The defense takes place at Campus Jussieu (4 Place Jussieu, 75 005 Paris). It is deserved by the metro lines 7 and 10 (Jussieu station), as well as by RATP bus lines 67 and 89.

The room number is 55-65-211: once on the campus, find the bar 55-65 (you can entry it by the tower 55 or 65), go up to the second floor and find the room 211.

If needed, click on the plan below and follow the tortoise!

Why should you come? Well, there are many good reasons. I will cite some of them (in a random order):

• You know me, you like me, and you know that I feel very comfortable in a crowd! So, do me a favour and come in great numbers!
• You want to meet members of my very cool committee:
  Rapporteurs:
  • Edith ELKIND, University of Oxford, Great Britain
  • Jérôme LANG, Université Paris Dauphine, France
  Examinators:
  • Jiehua CHEN, TU Wien, Austria
  • Jean-Paul DOIGNON, Université Libre de Bruxelles, Belgium
  • Nicolas MAUDET, Sorbonne Université, France
  Supervisors:
  • Bruno ESCOFFIER, Sorbonne Université, France
  • Olivier SPANJAARD, Sorbonne Université, France
• You are interested in structured preferences! Of course, this is THE reason to come. In my thesis, we study structural and algorithmic aspects of preference domain restrictions, namely single-peaked preferences and Euclidean preferences. An abstract can be found here.
• You enjoy eating karjalanpiirakka, ruisleipä, graavilohi... or you do not know what are these and want to discover them (and much more!) during my finnish-oriented after-defense "pot de thèse". Why finnish? Because I love Finland... and my thesis will be, I hope, fin(n)ished!

Don't worry! Please send me a mail, and I'll give you a link to the Zoom meeting.

If any of the above reasons (or another reason) make you want to come, and if you want to know more about my topics, I invite you to check this site Monday the 13th of March, 8 days before my defense. My disertation is divided into 7+1 chapters. Since Monday the 13th, every day, and for 8 days, a very brief summary of one of these chapters will be published here. The aim is to give you an opportunity to familiarise yourself with my subject, so that you fell more comfortable on the day of my defense, and you can enjoy it better!

Each of these summaries will be accompanied by a simple question to fix the notations, ensure yourself that you have understood, and to make you want to learn more! For the most motivated people among you, I suggest you the following game:

You can write down your answers and give them to me (by mail or in person) at the latest on the day of the defense. A few of the "best" participants will win a small homemade zero-waste accessory according to their choice (tote bag, sandwich bag, kitchen towel,...), decorated with a result of my thesis (there will also be a choice!). Looking forward to seeing you play the game!

The summaries are hidden in the following figure. At the end of each summary, Mathilde the tortoise has a simple question for you.

J1 (the 13 of March): quite a long summary to fix the most important notations and to introduce the notions of single-peaked, single-crossing and 1-Euclidean preferences.

J2 (the 14th of March): Relations between single-peaked, single-crossing and 1-Euclidean preferences.

J3 (the 15th of March): The first extension of single-peakedness: single-peakedness on an arbitrary graph.

J4 (the 16th of March): The second extension of single-peakedness: nearly single-peaked preferences.

J5 (the 17th of March): A very brief introduction to multidimensional Euclidean preferences.

J6 (the 18th of March): An algorithm for recognizing 2-Euclidean preferences.

J7 (the 19th of March): Euclidean preferences under the l_1 norm.

J8 (the 20th of March): The last one!

Finally, if you do not want to play, but you want to get familiar with my topic, here is a full (preprint!) version of my disertation.
