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.

"Kummer surfaces and hyperkähler fourfolds, as degeneracy loci"

Arturo Kohatsu-Higa (Ritsumeikan University, Kusatsu, Japan) gives a lecture with the title: Probabilistic interpretation of the parametrix method

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. 

Prof. Yasunori Fujikoshi​ (Hiroshima University​) will give a seminar in Sverdrups plass (lunch area), 8th floor, Niels Henrik Abels hus at 14:15.

The Logic Seminar will take place at the same time and location as in previous terms.

Andrea Cremaschi (earlier University of Kent, now UiO) will give a seminar in the lunch area, 8th floor Niels Henrik Abels hus at 14:15.

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.

Multi-index Monte Carlo and Multi-index Stochastic Collocation

Patrick Peter, Directeur de Recherche CNRS, IAP-Paris

In this talk I will present a paper by D. Bisch, R. Nicoara and S. Popa where continuous families of irreducible subfactors of the hyperfinite II_1 factor which are non-isomorphic, but have all the same standard invariant are constructed. In particular, they obtain 1-parameter families of irreducible, non-isomorphic subfactors of the hyperfinite II_1 factor with Jones index 6, which have all the same standard invariant with property (T).

Title: Enumerative Geometry of singular curves in a Linear System

Abstract: Enumerative geometry is a branch of mathematics that deals with the following question: "How many geometric objects satisfy certain constraints". A well known class of enumerative question is to count curves in a linear system H^0(X,L) that have some prescribed singularities. In this talk we will describe a topological method to approach this problem. We will express the enumerative numbers as the Euler class of an appropriate bundle. We will then go on to explain how we compute the degenerate contribution of the Euler class using a topological method.
