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 is open until June 10, 2022.  Registration is required if you wish to attend the social events and lunches served during the conference. (Pre-registration that included the options of requesting hotel room and applying for support has closed.)

Warning: You may receive unsolicited messages offering accommodations in Copenhagen during the conference, eg. from ehotelservices.org. Do not respond to any such messages. Any arrangements for accommodations made by the conference will be done by the math department, and not by any outside company.



This list is preliminary. More names will be added.









To be announced










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.

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.



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

Banquet Sunday july 3. The conference banquet will be held in parallel sessions! The main event is held at the Carlsberg Academy which very recently has been renovated. The banquet starts at 5 pm with beer (from Carlsberg!) and snacks and a stroll in the garden or in the Carlsberg Academy building, followed by a dinner in "Palmehaven".

Carlsberg Academy

The physical layout of the Carlsberg Academy sets a limit for the number of guests, so attendance to this event is limited by seniority to postdocs and up. Participants (who have preregistered, and as space allows, also those who register after preregistration has closed) and spouses are invited. (Due to the limited space, we may not be able to invite family members of participants beyond spouses.)

The younger participants (meaning PhD students and Master's students) are invited to dinner and beers in town guided by our local PhD students.







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.

















You can register for the conference by clicking HERE. Please register (again) even if you have preregistered. Registration closes on June 10.

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. 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.



For more information about the conference, contact Shabnam Abbasi at shabnam@math.ku.dk (for administrative questions including questions about accommodations) or one of the local organizers for scientific related questions) (see Organisers and Scientific Advisory Board)
