(Joint work with Paul Balmer.) We propose a categorification of the notion of Mackey functor for finite groups, intended to capture "higher" equivariant phenomena occurring throughout mathematics which are invisible to ordinary Mackey functors. Examples of such structures include familiar equivariant objects such as: (abelian and derived) categories of linear group representations, stable module categories, ...

In this talk, I will discuss some pathologies for the generic fibre of del Pezzo fibrations in characteristic p>0, motivated by the recent developments of the MMP in positive characteristic. The recent joint work with Stefan Schröer applies to deduce information on the structure of 3-dimensional Mori fibre spaces and answers an old question by ...

Abstract: We give an explicit construction of test vectors for $T$-equivariant linear functionals on representations $\Pi$ of $GL_2$ of a local field, where $T$ is a non-split torus. Of particular interest is the case when both the representations are ramified; we completely solve this problem for principal series and Steinberg representations of $GL_2$, as well ...

Abstract: Computational models are used nowadays in virtually all fields of applied sciences and engineering to predict the behaviour of complex natural or man-made systems. Those simulators allow the analyst to assess the performance of systems before actual manufacturing. They usually feature dozens of parameters and are expensive to run, even when taking full advantage ...

15th NCCR MARVEL Distinguished Lecture Several physical observables of materials have their theoretical root in geometrical properties of the electronic ground state. To start with, I will outline the modern theory of the insulating state, which addresses all kinds of insulators (band, Mott, Anderson...), discriminating them from metals by means of a very simple geometrical ...

Abstract: We give examples of progress made in Manin's conjecture in biprojective setting using the Circle method and show how Vaughan's result for an asymptotic Formula for the sum of 8 cubes can be gerneralized to deal with bidegree (1,3).

Sporting events


On May 1st, the challenge Bike to Work 2018 begins for a new edition until June 30th. In 2017, 646 students and members of staff formed 191 teams and covered 189,000 km, the equivalent of traveling almost five times round the Earth. It is our turn to take up the challenge and break this record! ... Read more about "Bike to Work"
