Operator algebras, dynamics and groups - an ICM satellite conference

Conference image

Copenhagen, July 1-4, 2022

The conference will bring together top researchers as well as early-career mathematicians in all areas of operator algebras with emphasis on applications to dynamics and group actions. The goal of the conference is to highlight the current status of the many directions that the field of operator algebras has taken, and to look at future challenges in the field.

The conference is a satellite event of the virtual ICM, July 6-14, 2022. The conference will also offer the possibility to the ICM speakers in operator algebras to deliver their ICM talk during the conference.

The 4-day long conference will start the morning of Friday July 1 and end early afternoon of Monday July 4. The conference program will include 25-30 talks. It is organized by the operator algebra group at the University of Copenhagen assisted by an international scientific advisory board.

Everyone is welcome to attend the conference. Registration has closed.  Registration was required if you wish to attend the social events and lunches served during the conference.

A booklet with titles and abstracts can be downloaded here: http://web.math.ku.dk/~rordam/OADG-2022/titles-abstracts.pdf.

All talks take place in Auditorium 4 in the HCØ (Hans Christian Ørsted) building at the mathematics department. 

The auditorium has ample blackboard space and a beamer, and it is possible to use both beamer and blackboard.

The conference will take place at the Department of Mathematical Sciences, University of Copenhagen. See detailed instructions on how to reach Copenhagen and the conference venue, and see this MAP of the HCØ building, where the conference takes place.

Tickets and passes for public transportation can be bought at the Copenhagen Airport and every train or metro station. You can find the DSB ticket office on your right-hand side as soon as you come out of the arrival area of the airport. DSB has an agreement with 7-Eleven, so many of their shops double as selling points for public transportation.

A journey planner in English is available.

More information on the "find us" webpage.

Directions from the airport to the conference hotels:

Traffic on June 30 and July 1 is heavily affected by the Tour de France. Most of the inner city is closed for traffic (except Metro and S-trains). It is therefore recommended that you use the Metro to get to your hotel. If you take a taxi, then be aware that the taxi driver may need to make a non-trivial detour to arrive at your hotel, and some of the hotels, for example Nora, cannot be reached all the way to its front door.

Hotel Nora: Take the Metro to Nørreport Metro Station (direct connection) and walk 850 meters (along Frederiksborggade, Dronning Louises Bro and Nørrebrogade) to the hotel.

Hotel CabInn Scandiavia: Take the Metro to Forum Metro Station (direct connection) and walk 400 meters (along Rosenørns Alle and Vodroffsvej) to the hotel.

Avenue Hotel: Take the Metro to Forum Metro Station (direct connection) and walk 500 meters (along Rosenørns Alle, Worsaaesvej and Åboulevarden) to the hotel.

9 Smaa Hjem: Take either the Metro or the regional train (aka Øresundstrain) to Østerport (Metro) Station. The metro is a more frequent and a bit faster but you need to change at Kongens Nytorv to the M3 or M4 line, while the regional train is direct. The Metro and the regional trains leave from different platforms (you walk up the stairs to get to the metro, and down the stairs for the regional train. The tickets for the two types of trains are the same. Walk 900 meters from Østerport Station to the hotel, eg. through Garnisons Cemetary.

Directions from the conference hotels to the math department:

Remember that on the first day of the conference, July 1, getting from your hotel to the math department you probably have to cross the route of the Tour de France. The race starts at 4 pm on July 1 and lasts until about 8 pm. It should be possible to cross the route, at least at selected places, when the route is free for bicycles and support cars.

If you are up for the adventure, you can rent a bicycle to get around. Unfortunately, there are no recommendable public transportation alternatives to walking (or biking) between the hotel and the math department.

Hotel Nora: Walk 1,5 km along Nørrebrogade, Fælledvej and Nørre Alle.

Hotel CabInn Scandiavia: Walk 2,5 km for example in parts along the lakes.

Avenue Hotel: Walk 2 km for example along Griffenfeldsgade, Nørrebrogade and Møllegade. You could take bus 1A (direction Hellerup St) to Rigshospitalet and walk from there, but it won't save you much time.

9 Smaa Hjem: Walk 2 km for example through Fælledparken.



Reception Friday July 1. Around 6 pm (after the lectures) we host a wine, beer and (light) food (Danish style smørrebrød) reception at the university for all conference participants.

Banquet Sunday july 3.  We all meet at the Carlsberg Academy which very recently has been renovated, at 5 pm for a beer and snacks and a stroll in the garden. Since seating space at the Academy is limited, the event hereafter branches off in two parallel sessions: the PhD students join the local PhD students to a night in town, and the more senior participants are served dinner in the "Pompeji" hall at the Academy. After dinner there is coffee in the "Palmehaven". The event closes around 10 pm.

Carlsberg Academy

The Carlsberg Academy is located in Valby and it has its own S-train station (called Carlsberg - easy to remember). Here is a map of how to get there. It's a bit far (but not impossible) to walk there from your hotel (it is 5 km from the math department). You may also wish to share taxis.







The conference has prebooked several rooms at four different hotels. Most of these rooms are already reserved during preregistration, but you can inquire into possible available rooms by writing to Shabnam at shabnam@math.ku.dk.

Availability of hotel rooms during the conference may be tight due to the "Tour de France"  (see the menu about the bicycle race below). With this in mind, here is some information for making your own hotel booking: We recommend Hotel 9 Små Hjem, which is pleasant and inexpensive and offers rooms with a kitchen. Other inexpensive alternatives are CabInn, which has several locations in Copenhagen: the Hotel City (close to Tivoli), Hotel Scandinavia (Frederiksberg, close to the lakes), and Hotel Express (Frederiksberg) are the most convenient locations; the latter two are 2.5-3 km from the math department. Somewhat more expensive – and still recommended – options are Hotel Nora and Ibsen's Hotel.

An additional option is to combine a stay at the CabInn Metro Hotel with a pass for Copenhagen public transportation (efficient and reliable). See information about tickets & prices.



Thanks to a grant from the Carlsberg Foundation, there are (limited) funds available to support PhD students and postdocs who wish to attend the conference. Application for support will be integrated in the registration form.

Deadline to apply for support has passed.

















Registration has closed.

It so happens that Tour de France for the first time in its history will visit Denmark in 2022, see HERE for more information.


The first leg of the famous bicycle race version 2022 will take place in Copenhagen on July 1 (the same day as our conference starts) with a 13 km time trial, starting at 16:00 and ending around 20:00 The following two legs will also take place in Denmark, but not in Copenhagen. You can find the route of the time trial HERE. It passes fairly close to the math department, which is located in the white triangle in the upper part of the map next to where it says "Niels Bohr Bygningen".

Besides offering a unique spectacle, the race will affect the conference in some other ways: Traffic including public transportation will be hugely affected - more information about how to get around that day will be posted when we get close to the conference. Hotels will be more difficult to book (we have made a number of block bookings in different hotels, see the accommodations information above), and even travel could be affected, so don't wait to the last moment buying your ticket to Copenhagen.
