Welcome to the Graduiertenkolleg/Research Training Group GRK 2240: Algebro-Geometric Methods in Algebra, Arithmetic and Topology. We are funded by the The Deutsche Forschungsgemeinschaft (DFG)
and located at the Heinrich-Heine-Universität Düsseldorf (HHU) and the Bergische Universität Wuppertal (BUW). The main goal of the research training group is the application of tools and results from Algebraic Geometry to pure
mathematics, for instance in nearby areas of Algebraic Topology, Group Theory, K-theory, Model Theory, Number Theory and Representation Theory. The emphasis is on the qualification of doctoral researchers within
the framework of a focused research program and a structured training strategy.

The German Research Council approved the second funding period for GRK 2240.

It runs from December 2022 to May 2027. The research training group
will grow from 9 to 11 principal investigators. The 5 new PhD positions in the fourth cohort are
expected to be advertised in October 2022.
