General overview

a) The conference will take place in the Science Faculty of the University of Artois from 8th till 11th of June 2015 .

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 delighted to announce that Professor Jay Wood from Western Michigan University ( Home page) will give the course this year (8 hours). We will have four main speakers:

  1. Frédérique Oggier, Nanyang Technological University, Singapore ( Home page).
  2. Christophe Reutenauer, Université du Québec à Montréal ( Home page).
  3. Angel del Rio, University of Murcia ( Home page).
  4. Irfan Siap, Yildiz Technical University ( Home page).

As in 2013, 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).

New features
For this fourth edition we will have:

  1. Poster sessions. There are volunteers but it would be good if some of you agreed to presnt a poster instead of giving a talk...
  2. books exhibitions. It will take place in the library itself. It will be open for all the duration of the conference.
    The AMS, Springer, Oxford, Elsevier will send books. The participants will receive a discount if they buy a book during the congress or a bit later...
  3. Some workshops or problem sessions, I need volunteers here as well.

Social and cultural event

The famous museum "Le Louvre" just opened "a branch" in Lens in 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 Bulding B room S.19 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.

    Meals

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

    Another algebra meeting in June at the faculty J. Perrrin

    From 15th June till 19th June, There will be another algebra meeting at the faculty Jean Perrin
    Linear algebraic groups, vector bundle classification and division rings
    The main speakers are:
    1. Jean Fasel (Institut Fourier, Grenoble): Some recent results on the classification of vector bundles over smooth affine schemes.
    2. Ulf Rehmann (Universitaet Bielefeld): Linear Algebraic groups and Algebraic K-Theory.
    3. Yoav Segev (Ben-Gurion University): Maps that resemble valuations on Division rings.
