Where do you store assignments? What about lists of personell information for a research group? What about their phone numbers? Do you have interviews of people? Pictures? What about research data? What kind of data is it? How to share different types of data with others in a functional and legal manner?  This talk will provide a practical guide for users in the current framework of laws and regulations. Attendance to the talk is highly recommended for everyone at the Department.

During the past 25 years there has been a significant activity constructing and analyzing C*-algebras and C*-algebraic dynamical systems from semigroups of number theoretic origin. Among these are the semigroup C*-algebras of the affine semigroup of the ring of algebraic integers in a number field, which are closely related to the Bost-Connes systems giving a thermodynamic interpretation of the Riemann and Dirichlet zeta-functions. The K-theory of the associated boundary quotients has been computed and also the phase transition of equilibrium states at low temperature has been exhibited via a natural parametrization. There is an intriguing, and still not understood, parallel in that the same C*-algebra lies at the heart of the solution of both problems. The goal of the master class is to introduce the participants to these and related topics lying at the intersection of several branches of mathematics.

 

The master class is a part of the project "Pure Mathematics in Norway, 2018-2022", supported by the Bergen Research Foundation and the Tromsø Research Foundation.

Title: Modeling the drift and radar backscatter signature of icebergs, by Ron Saper, Carleton University, Canada. 

Abstract: Icebergs are a source of wonder and mystery, and hide many mysteries that remain to be solved. In the quest to observe icebergs remotely and predict their behaviour, many difficulties are encountered and, at every turn, we find the expectations of engineers and researchers are frustrated. In this wide-ranging talk the many misconceptions and fallacies about icebergs are surveyed and analyzed, and their impact on scientific research and practice are explained and reflected upon. Examples are drawn from iceberg drift forecasting, remote sensing, and iceberg tracking studies.

Abstract:

A well-studied problem in computer vision is "structure from motion", where 3D structures and camera poses are reconstructed from given 2D images taken by the unknown cameras. The most classical instance is the 5-point problem: given 2 images of 5 points, the 3D coordinates of the points and the 2 camera poses can be reconstructed. In fact, given 2 generic images of 5 points, this problem has 20 solutions (i.e., 3D coordinates + 2 camera poses) over the complex numbers. Reconstruction problems which have a finite positive number of solutions given generic input images, such as the 5-point problem, are called "minimal". These are the most relevant problem instances for practical algorithms, in particular those with a small generic number of solutions. 

We formally define minimal problems from the point of view of algebraic geometry. Our algebraic techniques lead to a classification of all minimal problems for point-line arrangements and any number of cameras. We compute their generic number of solutions with symbolic and numerical methods.

This is joint work with Timothy Duff, Anton Leykin, and Tomas Pajdla.​
