"On the characterization of abelian varieties for log pairs in zero and positive characteristic"
Eric Priest, University of St.Andrews
Oleg Lebedev, University of Helsinki
I will discuss a special role of the Higgs boson in probing the hidden sector and its connection to dark matter and inflation.
(The slides will be available here)

Håvard Kvamme (UiO, Dept. of mathematics) will give a seminar in the lunch area, 8th floor Niels Henrik Abels hus at 14:15.
The Oslo Method in Inverse Kinematics
We will discuss the motivic May spectral sequence and demonstrate how to use it to identify Massey products in the motivic Adams spectral sequence. We will then investigate what is known about the motivic homotopy groups of the eta-local sphere over the complex numbers and discuss how these calculations may work over other base fields.

Welcome to the GeoHyd Lunch Seminar on Friday Sept. 16th @ 11:00 in aud. 1 in the Geology building.
Francesco Galuppi (UiO/Ferrara) gives the algebraic geometry seminar:
"Identifiability of polynomials and Cremona transformations."
Traditionally, population models are often built using only the female half of a population and males are considered nothing but "ecological noise". However, males do matter, and particularly so when there is sex-selective harvest going on.
This thursday, at the Speciation Journal Club, we will discuss a paper entitled
"Rapid evolutionary response to a transmissible cancer in Tasmanian devils" by Epstein et al. 2016 (Nature Communications).

Cell Culture Impedance Sensing with Thin Film ITO Electrodes
Certain 3-dimensional lens spaces are known to smoothly bound 4-manifolds with the rational homology of a ball. These can sometimes be useful in cut-and-paste constructions of interesting (exotic) smooth 4-manifolds. To this end it is interesting to identify 4-manifolds which contain these rational balls. Khodorovskiy used Kirby calculus to exhibit embeddings of rational balls in certain linear plumbed 4-manifolds, and recently Park-Park-Shin used methods from the minimal model program in 3-dimensional complex algebraic geometry to generalise Khodorovskiy's result. The goal of this talk is to give an accessible introduction to the objects mentioned above and also to describe a much easier topological proof of Park-Park-Shin's theorem.

Bartosz Kwasniewski (Odense) will give a talk with title: Paradoxicality and pure infiniteness of C*-algebras associated to Fell bundles
Abstract: Abstract: In this talk we present conditions implying pure infiniteness of the reduced cross-sectional $C^*$-algebra $C^*_r(\mathcal{B})$ of a Fell bundle $\mathcal{B}$ over a discrete group $G$. We introduce notions of aperiodicity, $\mathcal{B}$-paradoxicality and residual $\mathcal{B}$-infiniteness. We discuss their relationship with similar conditions studied, in the context of crossed products, by the following duos: Laca, Spielberg; Jolissaint, Robertson; Sierakowski, R{\o}rdam; Giordano, Sierakowski and Kirchberg, Sierakowski. (based on joint work with Wojciech Szyma{\'n}ski)
