From Higher Invariants

The Transatlantic Transchromatic Homotopy Theory Conference

Dates and Location

The conference will take place during the four days June 6-9, 2017 at the University of Regensburg. Here is the schedule. Aside from Wednesday afternoon, the conference will take place in Room D 2.121, building WNDE (Natural Sciences West). Registration and coffee breaks will be held nearby.

Aims and Scope

Transchromatic phenomena appear in a variety of contexts. These include stable and unstable homotopy theory, higher category theory, topological field theories, and arithmetic geometry. The aim of the conference is to bring together people from all of these areas in order to understand the relationship between each others work and to further demystify the appearance of transchromatic patterns in such disparate areas.

The conference will consist of 11 one hour long talks, six 30 minute long junior talks, and an open problems session.

Financial Support

Limited financial support for the conference and younger participants has been provided by the SFB 1085: Higher Invariants and SPP 1786: Homotopy theory and algebraic geometry.

The application deadline for financial support has passed.

Practical Information

MAP: Points of Interest.

University Map.

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 to the conference room from the 'Universitat' bus stop on campus, 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 6, 11, C6, and C11 towards campus can all be caught here and one of them stops at this stop about every 5 minutes during working hours.

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 for participants with limited financial support (all pre-PhD participants requesting financial support should request a shared room). Please refer to PROMOTION CODE "SFB 0617" 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

TRAVEL: One can reach the university by following the instructions here.

INTERNET: Access to eduroam is available throughout the mathematics building and the SFB building. For those without eduroam access we will obtain a temporary guest account through the university.
