Aim of the Workshop

The workshop on the Modular Isomorphism Problem will be held at the University of Murcia, Spain. It will bring together experts on various aspects of modular group algebras to discuss the recent developments around the Modular Isomorphism Problem and exchange ideas on further research.

If you have any questions please do not hesitate and write to us: adelrio@um.es

Dates

The workshop will be held from September 6th to 8th 2021. It will start in the afternoon on the 6th of September and finish around lunch time on the 8th.

Accommodation

The participants will be located in the hotel El Churra.
The center of Murcia is not big and completely accesible by foot. A direct tram to the University of Murcia, where the workshop will take place, departs from Plaza Circular.

Here are some links with interesting sites in Murcia and its surroundings.



Arrival

For international arrivals the airport of Alicante is the closest airport. From there buses are available to the city of Murcia. The bus ride takes about one hour and a schedule is available here. To take the bus to Murcia exit the airport and walk right until you reach the bus stop at the end of the sidewalk. A ticket can be bought directly at the bus stop. Note that the last bus on Sundays already departs at 19:15h and the bus schedule has been reduced heavily recently.

Alternatively, it is possible to take a bus to the Bus or Train station of Alicante and travel to Murcia from there. Note that there are also many cercanias running between Alicante and Murcia which sometimes do not appear on train searches.

In case you can not take the bus, a taxi from the airport to the city of Murcia costs around 120 Euros. For arrivals from other Spanish cities bus and train services are available, please check the websites of Renfe and ALSA for more information.
