Geometry and Topology, ICM sectional workshop

The International Congress of Mathematicians (ICM) is the world's largest mathematical meeting. Taking place every four years, it presents a unique opportunity for interaction of mathematicians from the whole world and across all mathematical disciplines.

The ICM 2022 was recently reorganised as an online event, and this event will host some of the talks real life, and attempt to salvage, on a smaller scale, some of the usual spirit of an ICM. The focus of the event in Copenhagen will be the Geometry and Topology sections, though it will not be restricted to those. Similar events are being organized at other locations, see links below.

All the talks of the ICM 2022 will be streamed and we also plan "public viewings" of ICM talks held at other locations, see below for the speakers who will be present in Copenhagen. We expect to have limited financial support for junior participants and will hold short communications sessions for junior participants.

We are looking forward to an exciting and lively mini-ICM 2022 in Copenhagen!

You can either participate in person 🇩🇰 or online 🌎 through the official virtual ICM

See the program for the Virtual ICM 2022 at the IMU webpage.

Our local program in Copenhagen will be available soon.










The talks will take place at the Department of Mathematics, University of Copenhagen, H. C. Ørsted Institute, Universitetsparken 5, 2100 København Ø. See detailed instructions on how to reach Copenhagen and the department.

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.







We kindly ask the participants to arrange their own accommodation.

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.













Please register before June 15 by filling the form Registration form. If you want to apply for funding, you need to register by April 30.
