We are happy to announce the new Collaborative Research Centre "Generalised Motivic Methods in Geometry" (CRC 1785, funded by the DFG) at the University of Regensburg, in collaboration with colleagues from the University of Augsburg, TU Munich, and JGU Mainz.
The idea of this CRC is to promote and further develop motivic thinking in a wide variety of geometric contexts, such as algebraic/arithmetic geometry, topology, and Riemannian geometry.
This CRC offers a workshop and guest programme and a number of PhD and postdoc positions.
