Workshop "Operads and Homotopy Theory"

Informal workshop to be held at the University of Lille, on August 23-28, 2010.

Dates : opening buffet on Monday 23 August at 12:00, closing on Saturday 28 August at 12:00.

Place/Practical information :

The workshop will be held at the UFR de Mathématique, of the Université Lille 1, campus "Cité Scientifique". Talks will take place in the "Salle de Réunion", building M2 of the math department. The welcoming buffet lunch, for the arrival of participants on Monday, will be served in the same building. Participants are lodged at the hotel Ascotel, in the campus, 100m far from the math buildings. From Tuesday till Friday, we will take lunch meals at the "Restaurant Universitaire Parisel", on another side of the campus. We have booked cold meals and sandwiches for Saturday noon.
The campus "Cité Scientifique" is connected to the main train stations of Lille and to the center of the city by an efficient, fully automated, subway line, running from 5am till 12pm (expect 20mn to get the campus from the train stations). If you come from overseas, then the easiest is to arrive at Paris-Charles-de-Gaule-Airport, and to take a TGV at the airport station (terminal 2) going to Lille in 50mn. Lille train station is also the terminus of several Belgium lines coming from Antwerpen and Bruxelles, and a halt of the Eurostar line "London-Bruxelles". The campus is also close to the airport of Lille which offers several connections to French and European cities.

Program :

The program of the talks will mostly be decided during the workshop, in the spirit of the MPI "Arbeitstagung". We just intend to fix the program of the first days - Monday and Tuesday - in advance and to prepare a tentative program for the remaining of the workshop, on the basis of participants' proposals. Please send talk propositions or suggestions to: . The titles/abstracts which we have already received are recorded below on this page.
We encourage the submission of propositions in advance, but we have scheduled a discussion about the workshop program on Monday evening to allow late suggestions. We plan five talks per day. From Tuesday till Saturday, we plan to devote each half day to a specific topic, or to gather together talks relying on close thematics. We have already planed the schedule of some talks with this idea in mind. Thursday afternoon will be free and a banquet will be organized on Thursday evening.
