In this talk we discuss the local-global principle for integral solutions to systems of two (inhomogeneous) quadratic equations. In particular we will see concrete examples of Brauer classes obstructing the Hasse principle and discuss obstructions to the local-global principle in more general. This is joint work with Joerg Jahnel. Read more about "On integral solutions to systems of two quadratic equations"

Acylindrically hyperbolic groups form a vast collection of groups including non-elementary hyperbolic and relatively hyperbolic groups, mapping class groups, Out(F_n), many groups acting on CAT(0) cube complexes, and many others. I will present a few results that describe their bounded cohomology in terms of their so-called hyperbolically embedded subgroups and, time permitting, discuss an expected ...

Abstract: The life-cycle management of structural systems operating under diverse loads involves the tasks of simulation (forward engineering), identification (inverse engineering) and maintenance/control actions. The efficient and successful implementation of these tasks is however non-trivial due to the ever-changing nature of these systems, and the variability in their interactive environments. Two defining factors in understanding ... Read more about "A Monitoring Approach to Smart Infrastructure Management"

Morel-Voevodsky's motivic stable category of schemes plays a crutial role in today's stable homotopy. For instance, a recent work of Isaksen-Wang push our knowledge of stable stems up to dimension 93. In this joint work with Achim Krause and Bogdan Gheorghe, we construct a new model category, equivalent to the cellular motivic stable category, but ...

I will describe the geometry of the 2m-dimensional Fano manifold G parametrizing (m-1)-planes in a smooth complete intersection Z of two quadric hypersurfaces in the complex projective space of dimension 2m+2. We will see that there are exactly 2^{2m+2} distinct isomorphisms in codimension one between G and the blow-up of P^{2m} at 2m + 3 ...

This conference will conclude the semester program on "Euler Systems and Special Values of L-functions". The goal will be to present recent advances in the constructions of Euler systems, their applications to the Birch and Swinnerton-Dyer conjecture and Iwasawa theory. Emphasis will be given on novel results obtained during the semester. Read more about "Recent Developments on the Arithmetic of Special Values of L-functions"

I will describe how monodromy groups of the hypergeometric differential equation can give rise to quadratic forms over the rational integers. By computing invariants of these quadratic forms, we can say something about commensurabilities among these monodromy groups.

I will discuss some recent joint work with Yongxiong Li which shows how one can use Iwasawa theory at the neglected prime p=2 to prove stronger versions of an old theorem of David Rohrlich on the non-vanishing of Birch-Swinnerton L-values of the Gross family of elliptic curves with complex multiplication, and discuss some possible generalisations.

I'll discuss the basics of quantum computing, how Shor's algorithm allows a quantum computer to factor numbers efficiently using the quantum Fourier transform. I'll try to convey as much intuition as possible, to explain the relevant basics of quantum mechanics, and to give an idea of the capabilities of quantum computers.

In this presentation I will highlight the great potential offered by the interplay between data science and computational science to efficiently solve real life large scale problems. The leading application that I will address is the numerical simulation of the heart function. The motivation behind this interest is that cardiovascular diseases unfortunately represent one of ...
