Winter School in $\mathbb{A}^1$-Homotopy Theory

As part of the cooperation between the FRIAS Research Focus on “Cohomology”, the Research Training Group GK1821 and the SPP 1786 progrqm “Homotopy Theory and Algebraic Geometry”, we are pleased to announce a  winter school on $\mathbb{A}^1$-Homotopy Theory that will take place in Freiburg from February 5 to 9, 2018.

The school will cover the basic constructions of the unstable and stable $\mathbb{A}^1$-homotopy categories, along with the relevant category-theoretic methods, such as model structures, left Bousfield localization and symmetric spectra. These constructions will be applied to more recent developments, such as the questions of $\mathbb{A}^1$-contractibility and the minus-part of the stable $\mathbb{A}^1$-homotopy category.

Please see our web page for more information.

Activities and Visitors in Winter

FRIAS fellows Frédéric Deglise, Johannes Nicaise and Gisbert Wüstholz are currently in residence, and are joined by Bradley Drew, Oliver Bräunling and Matthias Wendt from the side of the math department. Jorge Pereira will join us in December, Gerard van der Geer will come in January.
