Revision as of 14:32, 2 October 2017
Workshop: NonPositively Curved Groups and Spaces
The workshop will take place during the week September 1822, 2017 at the Faculty of Mathematics of Universität Regensburg.
The talks will be in the lecture hall H51, which is close to the Biology part of the campus; see the University Map.
 Conference dinnere will be here > Google maps
 Abstracts of minicourses and talks: pdffile.
 Slides 1, Slides 2, Slides 3 and excercises of Jon McCammond.
Retraction of Jon McCammond: In the course I claimed that braid groups are CAT(0). Unfortunately, we have found a mistake, so we have had to retract our claim.
 The poster is available here: link.
Please note that in the week following the Workshop, the Conference: Manifolds and Groups takes place at the same location!
NonPositively Curved Groups and Spaces is the third in a series of workshops organized in Regensburg. The second was on Large Scale Dimensions and the first was on Cohomology and Large Scale Geometry.
Registration
Registration is now closed. If you want to attend, please send an email to one of the organizers.

Guided Tour
We will visit the Old Town Hall (Reichstagsmuseum). The tour is entirely inside the building, thus it will take place regardless of the weather. We are going to meet at 17:25 in front of the information office (or inside in case of rain) at Rathausplatz (see the map).

Practical Information
 TRAVEL: In order to reach the university kindly follow the instructions here.
 INTERNET: Access to eduroam is available throughout the mathematics building.
MAP: Points of Interest.
PUBLIC TRANSIT: Local bus system and route map.
There are many useful buses typically, but the 6 will suffice for getting to and from the city center and the conference room (nearest stops are either 'An der Kreuzbreite' or 'Neuprull'). There should be signs pointing to the lecture hall.
One can also walk from the 'Universitat' bus stop, which is better served by the bus system. The 6, 11, C6, and C11 buses all travel between the HBF (central station) and the Universitat bus stop. The above maps may prove helpful.
You can pay for a bus ride on entering the bus or purchase a strip of tickets from one of the ticket machines. A strip of tickets costs 9.00 euros and it allows five bus rides.
ACCOMMODATION: We have reserved a block of hotel rooms at the Hotel Apollo. Participants will need to book and pay for their own accommodation, although the Hotel Apollo should be able to arrange shared rooms (double / twin) for participants with limited financial support (all prePhD participants requesting financial support should request a shared room). Please refer to PROMOTION CODE "SFB 0917" when making a reservation!
Regensburg is a tourist destination and we encourage guests to book their rooms as early as possible. Here is a list of hotels in the area:
1. Hotel Kaiserhof am Dom (In the city center, must take a bus to the University.)
2. Hotel Muenchner Hof (In the city center, must take a bus to the University.)
3. Hotel Apollo (Near the conference, but limited eating options.)
4. Hotel Jakob (In the center, must take a bus to the University.)
5. Hotel Central (In the city center, must take a bus to the University.)
One can also check the standard alternatives:
1. Hotels.com
2. Airbnb
Please use this Google sheet to find a roommate.
