From Higher Invariants

Conference on invertible objects and duality in derived algebraic geometry and homotopy theory

Dates and Location

The conference will take place during the week April 3-7, 2017 at the University of Regensburg in the biology wing, lecture hall H51.

Aims and Scope

The aim of this conference is to present recent advances related to the study of invertible objects, duality, and higher invariants in derived algebraic geometry and homotopy theory. In particular, this conference will include talks on the recent breakthroughs in the study of units, Picard groups, Brauer groups, twists, and module categories.

The activity will consist of a four-part lecture series as well as a number of invited lectures. There will also be an opportunity for junior participants to make short presentations.


Invited lectures

Financial Support

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

All applications for financial support received by December 15th, 2016 will be given full consideration.


Please fill out the registration form.

Statement of Inclusiveness

We (the organizers) affirm that scientific events have to be open to everybody, regardless of race, sex, religion, national origin, sexual orientation, gender identity, disability, age, pregnancy, immigration status, or any other aspect of identity. We believe that such events have to be supportive, inclusive, and safe environments for all participants. We believe that all participants are to be treated with dignity and respect. Discrimination and harassment cannot be tolerated. We are committed to ensuring that this conference follows these principles.

Practical Information

MAP: Points of Interest.

University Map.

PUBLIC TRANSIT: Local bus system. There are many useful buses typically, but the 6 will suffice for getting to and from the city center and the conference hall (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 above maps may prove helpful.

ACCOMMODATION: We will reserve a block of hotel rooms at the Hotel Apollo. Participants will need to book and pay for their own accommodation (promotion code SFB 1085), 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).

Regensburg is a tourist destination and, although April is low season, 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 and biology building. For those without eduroam access we will obtain a temporary guest account through the university.
