General overview

a) The conference will take place at the Science Faculty of the University of Artois from 12th till 15th of June 2017 .

b) As for the previous editions of this conference, the aim is to gather specialists in ring theory and in areas where this theory is used (for example in representation theory, coding theory, cryptography).
I am very happy to announce that Professor Frédérique Oggier from Nanyang Technological University, Singapore ( Home page) will give the course this year (8 hours). We will also have four main speakers:

  1. Philippe Langevin, Université de Toulon (France) ( Home page).
  2. Christian Lomp, University of Porto (Portugal) ( Home page).
  3. Sergio Lopez-Permouth, University of Athens (Ohio, USA) ( Home page).
  4. Pace Nielsen, Brigham Young University, Salt lake city (USA) ( Home page).

The course and the plenary talks will take place in the mornings.
In the afternoons the participants will have the possibility to present their works during short talks (20-25 minuts each).

Poster sessions, Book exhibitions, Workshops

  1. Poster sessions. You are welcome to present a poster. They will stay visible not only during the poster sessions but for at least a whole day.
  2. Books exhibitions. I'll try to organize it as in 2015. It will be opened during all the conference.
  3. For Some workshops or problem sessions, I need volunteers here as well. If you have some questions or open problems that look somewhat close to the themes of the conference, do not hesitate. If you think it could be useful to post these earlier on the web, just send me a file...

How to register

The registration is now closed....but you can always write to me... André Leroy


Group 1 and Group2 Some Participants at work! IMG_20170612_091330 Frédérique Oggier starts the course!, P1, P2, P3, P4, P5, P6, P7, P8, P9, P10, P11, P12, P13, P14, P12, If you have nice pictures taken at the conference that you would like to see on this web page, just send them to me! Liang Shen sent me the following ones (Thanks for these) P13, P14, P15, P16, P17, P19,

Social and cultural event

A banquet will be organized (around 20 Euros)... More about this subject later. The famous museum "Le Louvre" has "a branch" in Lens since December 2012. They organise regular exhibitions and this is for sure an easy target. Another possibility is to visit Arras or Lille... Here are some link for "Le Louvre Lens" Louvre II or also the following one.

Arriving in Lens

BY PLANE There are 4 different airports not too far from Lens;

  • Lesquin (International Air Transport Association: LIL). This the airport of Lille (the biggest city in north of France) It is the closest (35 km from Lens). If you arrive via this airport you will have to take a bus to the Lille railway station (Lille Flandres) and then take a train to Lens. Notice that as far as I know there are no connection by plane between Charles de Gaulle airport and Lesquin so even if your ticket plane says that you have a stop in CDG and then go to Lesquin it is highly probable that this last part of your journey (from CDG to Lesquin) will be by train!
    Lesquin (Lille) airport

  • Charles de Gaulle at Roissy (IATA code: PAR; ICAO code: CDG). This is the most likely airport of arrival if you are coming from abroad. There is a train station and you can connect directly to Lens or go to Lille and in Lille take a train to Lens (this is sometimes faster since there are not too many direct train from CDG to Lens).

    Connection between CDG airport and Lens Train from CDG airport

  • Beauvais (IATA code BVA) This airport is very close to the city of Beauvais (Tillé). You could arrive to this airport specially if you use low fare airlines. There is frequent bus shuttle to the center of Beauvais and from there you can take a train to Lens via Paris nord 'and possibly with a stop in Arras)

  • Charleroi (IATA code CRL) This airport is in Belgium (also called Brussels south airport). This airport is not too far from Lens but you will have to take a shuttle to Brussels or to Charleroi and then take a train to Lens (probably via Lille). There are quite a few low cost companies using this airport.
    Charleroi Airport
    NOTE !!: if you want to arrive via this airport and need a visa, be sure you are OK. I think you need a visa from the country you are entering Europe so in this case this would mean Belgium....

    BY CAR From Paris take the A1 in direction of Lille and in Hennin Beaumont take the A 21. Leave this highway at Lens centre. The building of the "faculté Jean Perrin" is very close to the Bollaert stadium. This building is known as the "batiments des mines".

    BY TRAIN You can get information on the connections at the following URL

    The faculty Jean Perrin

    The talks will take place in the Bulding of the "Faculté Jean Perrin". This Faculty is part of the university of Artois. The address is "23 Rue Jean Souvraz, Lens, France". It is located in a very nice and impressive building that served as offices for the coal mines till the 60's. It is still known as "le bureau des mines" by the local population. It is about 15 minutes walk from the train station and is quite close to the "Stade Bollaert" (a footbal (i.e. soccer) stadion). In front of the faculty building there is a nice park where you can have a walk and relax or just think and solve your math. problems!
    Here is a picture: map of Lens
    The picture of the faculty is on my web page.

    Hotels and accomodations

    A) Hotels I can reserve a room for you but of course you can do this directly as well (if you want me to do so, please mention it while registering since I'll try to get some discount for the participants).
    1) The closest hotel is the Hotel Bollaert. Here is a link for the hotel Bollaert
    2) The hotel "Campanile Lens" is not too far (about 30 minuts walk). If you have a car... Here is a link for the hotel Campanile
    3) The hotel "Le Paris Brest-Brest" is located nearly in front of the train station. This means at about 15 minuts walk from the faculty. For more information on this hotel click here
    4) Just in front of the station: Hotel de France, 2 Place du Général de Gaulle.


    The breakfasts and the lunches will be offered to all the participants during the congress.
