With Euler and Riemann, a magical object entered mathematics: the zeta function. The magic lies in the fact that the mysterious ways of complex analysis can be made to bear fruit on problem in combinatorics, number theory, dynamics or geometry. In the talk, I will first show some of the traditional magic, and then discuss why it is interesting to replace "one zeta function" by "many zeta functions": the new philosophy is that several structures (such as Riemannian manifolds and number fields) - that are maybe not uniquely determined by one zeta function - can be completely captured by such a family of zeta functions (joint work with Matilde Marcolli and Jan Willem de Jong).

In the academic year 2019-2020, the University of Groningen will start a Master’s degree programme in Mechanical Engineering. The engineer Prof. Jacquelien Scherpen, who presides the Groningen Engineering Center (GEC), has referred to the programme...
For many years now, Maarten Loonen has seen first-hand how the climate has changed on Spitsbergen. He can talk for hours about geese, reindeer, glaciers and the immeasurable, still undiscovered nature on the Norwegian island. His main concern, though,...
The Top Master's programme in Nanoscience has been assessed by an international peer review committee, organized by QANU, and their report has now been published and confirmed by the NVAO (Accreditation Organisation of the Netherlands and Flanders)...
