General overview

a) The congress took place from July 1st till July 4th in the Science Faculty of the University of Artois.
b) The aim was to gather specialists in ring theory and in areas where this theory is used (for example in coding theory and cryptography). Prof. Steven Dougherty gave a course showing some of the ways (noncommutative) ring theory has influenced coding theory. The 4 invited speakers were: Alberto Facchini, Dolors Herbera, Edmund Puczylowski and Patrick Solé. Participants will have the possibility of presenting their results.

Proceedings

If enough participants are ready to submit an article there will be a proceedings. The papers submitted will be refereed in a classical way. The scientific committee will serve as an editorial board. Contact with potential publishers will soon be taken. Please do consider to submit such an article.
The AMS contemporary Math. series have given a preliminary approval for publishing the proceedings of the conference.
You will soon be contacted by Christine Thiverge (from AMS contemporary Math.) about this. Please do consider to submit an article.

Social and cultural event

The famous museum "Le Louvre" just opened "a branch" in Lens (It was inaugurated by the French President on 4th December 2012). This is the result of a very long history. I have not yet visited the museum, but I'll do it soon, for sure. It is at walking distance from the faculty and it seems that the museum will be...free during the first year. Here are some links....take a look! 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 "Faculté Jean Perrin", probably in room E7-E8 in the building A. 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". In front of this 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 map of Lens
    The picture of the faculty is on my web page.

    Hotels

    I can reserve a room for you but of course you can do it directly as well (if you want me to do so, please mention it while registering).
    1) The closest hotel is the Hotel Bollaert. I get a special discount for the participants: a single room without breakfast will cost 75 Euros/night. 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

    Meals

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