## Conferencence and Workshops

### 2016

### April

### Conference: Generalizations of A^{1}-Homotopy Invariance in Algebraic Geometry and Homotopy Theory

**Location/Dates:** Haus Kranich-Usedom, April 3, 2016 (arrival) to April 8, 2016 (departure).

**Organizers:** Jose Burgos, Hélène Esnault, Moritz Kerz, Jürg Kramer

**Topic:**
We plan to have an exchange on A^{1}-invariance in topics ranging from constructions of non-A^{1}-invariant motives and ramification in arithmetic geometry, as well as their relation with Arakelov geometry.

### Juni

### Conference: Motivic homotopy groups of spheres

**Location/Dates:** University of Duisberg-Essen in Essen, June 21-25, 2016.

**Organizers:** Aravind Asok, Marc Levine, Oliver Röndigs

**Topic:** motivic homotopy theory

### September

### Workshop: Differential forms in algebraic geometry

**Location/Dates:** Universität Freiburg, Sept. 19-23 2016.

**Organizers:** Manuel Blickle, Annette Huber, Stefan Kebekus, Shane Kelly

**Topic:**The aim of the workshop is to bring experts from the field of motive, homotopy theory and derived algebraic geometry together with specialists in bi- rational geometriy and algebraic geometry in characteristic p. The different groups will be able to learn about each other’s problems and methods.
