## Topology Seminar: Injective and projective model structures on enriched diagram categories

K. Hess, M. Kedziorek, E. Riehl, and B. Shipley have developed methods to induce model structures from an adjunction which they apply to prove the existence of injective and projective model structures on categories of diagrams in accessible model categories. In this talk, I will explain how to adapt their proof to an enriched setting, ...

## On integral solutions to systems of two quadratic equations

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.

## A Monitoring Approach to Smart Infrastructure Management

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 ...

## Topology Seminar: A model for Motivic stable homotopy in classical homotopy

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 ...

## On the Fano variety of linear spaces contained in two odd-dimensional quadrics

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 ...

## Recent Developments on the Arithmetic of Special Values of L-functions

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.

## Bernoulli Lecture - Non-Vanishing of some Birch-Swinnerton-Dyer L-values

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.

## Quantum computing for amateurs (by an amateur)

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.

## Structure and dynamics of Polish groups conference

Polish topological groups comprise all locally compact second countable groups, but also most interesting topological transformation groups such as homeomorphism and diffeomorphism groups of compact manifolds, isometry groups of separable complete metric spaces, and automorphism groups of countable model theoretical structures. While all of these classes had been intensively studied separately, there has recently been ...

## Large scale geometry of Polish groups workshop

The topic of this workshop will be geometric group theory in a larger context. As is well known, there are close links between geometric group theory of finitely generated or locally compact groups and geometric non-linear functional analysis, i.e., the non-linear geometry of Banach spaces. While this has for a long time been seen as ...

## Prof. Alfio Quarteroni: "Taking Mathematics to Heart"

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 ...
