General overview

a) The conference will take place at the Science Faculty of the University of Artois from 24th till 27th of June 2019.

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 Cary Huffman from Loyola University in Chicago ( Info ) will give the course this year (8 hours). We will also have four main speakers:

  • Walter Ferrer , Universidad de la republica Montevideo (Uruguay)
  • Agata Smoktunowicz, University of Edinburgh (UK) ( Info).
  • Pedro A. Guil, University of Murcia (Spain) ( Info ).
  • Michal Ziembowski, Warsaw University of Technology (Pologne) (Info).
    The course and the plenary talks will take place in the mornings (Room S25).
    In the afternoons the participants will have the possibility to present their works during short talks (20-25 minutes each, room S.25).


    With the kind permission of Prof. Cary Huffman here is the content of his First lecture
    Second lecture.
    third lecture.
    fourth lecture.

      Proceedings

      There will be a proceedings for the NCRA, VI conference. The final approval is not yet reach...In fact, it is not yet clear if the proceedings will be published by Springer or by the AMS (contemp. math. series). The papers submitted will be refereed in a classical way. The scientific committee will serve as an editorial board. Consider seriously to submit a paper!
      Deadline for submitting an article : 15 december 2019. Please do consider to submit an article.

    Thanks to Arkadiusz Mecel for these ones


    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 connections

    Back to top of the page

    The faculty Jean Perrin

    The talks will take place in the Bulding B Aula S 25 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.
