Singularities of Restriction Varieties in OG(k,n)
In the nineties, Deninger gave a detailed description of a conjectural cohomological interpretation of the (completed) Hasse-Weil zeta function of a regular scheme proper over the ring of rational integers. He envisioned the cohomology theory to take values in countably infinite dimensional complex vector spaces and the zeta function to emerge as the regularized determinant of the infinitesimal generator of a Frobenius flow. In this talk, I will explain that for a scheme smooth and proper over a finite field, the desired cohomology theory naturally appears from the Tate cohomology of the action by the circle group on the topological Hochschild homology of the scheme in question.
Abstract: Exploring connections between subfactors and conformal field theories, Vaughan Jones recently observed that planar algebras give rise to unitary representations of the Thompson group F, and more generally, to unitary representations of the group of fractions of certain categories. Remarkably, this procedure applies to oriented link invariants. In particular, a suitably normalized HOMFLYPT polynomial is a positive definite function on the oriented Thompson group. (Based on joint work with V. Aiello and V. Jones.)
The motivic Adams spectral sequence is a general tool for calculating homotopy groups of a motivic spectrum X. We will investigate the construction of the motivic Adams spectral sequence, determine the second page of the spectral sequence, and identify what it converges to in good cases. If time permits, we will show how to use the motivic Adams spectral sequence to obtain explicit calculations of the motivic homotopy groups of spheres and other spectra.
On 5-7 September the first STORE PHD Gathering will take place, with two intensive courses. The first is on the new class of stochastic processes called Trawl processes and instructed by Almut Veraart from Imperial College London, UK. The second is led by Rudiger Kiesel from University of Duisburg-Essen, Germany, and focuses on intra-day trading of electricity.

Arturo Kohatsu-Higa (Ritsumeikan University, Kusatsu, Japan) gives a lecture with the title: Probabilistic interpretation of the parametrix method
ESOP seminar. Sonja Fagern?s is Lecturer in Economics at Sussex University. She will present a paper entitled "Teachers, Electoral Cycles and Learning in India", written jointly with Panu Pelkonen.
The upcoming Friday Mingle will be special. The MSc graduates of summer 2016 will receive their diplomas. The newly enrolled MSc students will also be there. And there will of course be room for chat and eating of cake.
After the Friday Mingle - at 12.00 - there will also be a BBQ in the garden.
Hope all of you are able to attend.

Bloch constructed higher cycle class maps from higher Chow groups to Deligne cohomology and étale cohomology. I will define a map from the motivic Eilenberg-Mac Lane spectrum to the spectrum representing Deligne cohomology in the motivic stable homotopy category over C such that it gives Bloch's higher cycle class map on cohomology. The map is induced by the map from Voevodsky's algebraic cobordism spectrum MGL to the Hodge-filtered complex cobordism spectrum defined by Hopkins-Quick. This extends a result of Totaro showing that the usual cycle class map to singular cohomology factors through complex cobordism modulo the coefficients of the Lazard ring MU^{2*} tensor_L Z. This is joint work with Amit Hogadi.
