Invited Speakers

And there will be the opportunity to present a contributed talk!

Aim of the Conference

The conference "Groups and their actions: algebraic, geometric and combinatorial aspects" will be held at the BellaVista Relax Hotel, Levico Terme, Italy between June 3nd and 7th 2024.
The aim of the conference is to bring together experts and young researchers working on different aspects of group actions to interchange ideas, with special emphasis on learning about each other's viewpoints. For example, on one hand during the last century representation theory has built a rich toolbox for actions on modules, while on the other hand, for instance the study of monoidal categories and tensor triangular geometry introduced a quite different point of view. Recently group actions on more general algebraic, geometric and combinatorial objects, in the form of a plethora of moduli spaces and associated invariants, have given new perspectives. The presentation of these various aspects and their interaction is the main idea of the conference.

There will be the possibility for participants to present a contributed talk. Please indicate when registering, if you would be interested to do so. We have some limited funding available to support the participation of early career researchers.

Dates

The talks will begin Monday morning, June 3rd, and finish on Friday June 7th around noon. Arrival is expected on Sunday June 2nd and departure on Friday June 7th or on Saturday June 8th.

Registration

The registration has been closed on April 21st. If you have any doubts, please write to us: gaagc24@gmail.com

There is only a limited number of places available for participants. For practical reasons all participants should lodge at the conference venue; it will not be possible to provide refreshments and meals for guests sleeping elsewhere (unless they are affiliated with the University of Trento). To be sure that no place is wasted, we count a registration as complete once the hotel has been officially reserved. Instructions on how to do this will be sent soon to the registered participants. Some of the rooms are only available as double rooms and we encourage the participants to share a room where this is not too restrictive.

Event schedule

You can download the abstracts of all talks at once in the abstract book below. A talk schedule is included on the last page and is also separately downloadable. There might still be some minor changes.

Italy

The BellaVista Relax Hotel can be reached with a 20 minute walk from the railway station Levico Terme.

Getting from Trento to Levico Terme

To reach Levico Terme the easiest way is to reach Trento's railway station and take a train from there. The last train is at about 8pm on Sundays and 9pm during the week and they are frequent throughout the day. For the timetable check Trenitalia's webpage.

Getting to Trento

If you won't be reaching Trento by train, the following is a short list of possible airports you can travel to:

  • "Valerio Catullo", Verona (about 90 km from Trento). To get from this airport to Trento's railway station you can take a bus (running every 20 minutes) to the station of Verona Porta Nuova and then take a train from there to Trento (the timetable is again available on Trenitalia's webpage).
  • "Guglielmo Marconi", Bologna (about 200 km from Trento). To get from this airport to Trento's railway station you can take the Marconi express (running every 10 minutes) to the station of Bologna Centrale and then take a train from there to Trento (the timetable is again available on Trenitalia's webpage).
  • "Marco Polo", Venezia (about 150 km from Trento). To get from this airport to Trento the best, most direct way, is to take a Flixbus, which will leave you at a 10minutes walking distance from Trento's main station. Make sure to check the timetable and the availability of tickets before booking your flight. It is also possible to go another, more complicated way. You can take a shuttle bus to the station Venezia-Mestre and then take a train connection to Trento from there (direct trains are very rare!).
  • "Leonardo da Vinci", Roma-Fiumicino (about 600 km from Trento). To get to Trento from this airport you can first take the Leonardo express (non-stop service dedicated exclusively to airport passengers, departing every 15 minutes with travel time of about 30 minutes) to the station of Roma Termini and then a train to Trento (the timetable is again available on Trenitalia's webpage).
  • "Milano Malpensa", Milano (about 250 km from Trento). From this airport you can take the Malpensa express (dedicated to airport passengers) to the station of Milano Centrale and then a train to Trento (the timetable is again available on Trenitalia's webpage).
  • "Orio al Serio", Milano-Bergamo (about 180 km from Trento). To get from this airport to Trento the best, most direct way, is to take a Flixbus, which will leave you at a 10minutes walking distance from Trento's main station. Make sure to check the timetable and the availability of tickets before booking your flight.
