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.

Matematisk institutt inviterer tidligere studenter til å møtes. Det blir litt faglig, mye sosialt og mulighet for å møte igjen gamle medstudenter på campus.

You are cordially invited to an afternoon of three seminar talks on recent topics in stochastic analysis in high dimensions. The talks take place at the Wolfgang Pauli Institute in Vienna, Austria (https://www.wpi.ac.at).

Kenny De Commer (Vrije Universiteit Brussel, Belgium) will give a talk titled: Spectral *-algebras and quantum group actions

Lara Lusa (Department of Mathematics, University of Primorska, SLO) will give a talk on September 3rd at 14:15 in the Erling Sverdrups plass, Niels Henrik Abels hus, 8th floor.

Prof. Andrey Pilipenko from The National Academy of Sciences of Ukraine will give a seminar lecture with the title:

On Exponential Stability of SDEs with Discontinuous Drift

The scope of the workshop: This international workshop brings together scientist from a wide range of fields with a special interest in bio-mechanics phenomena from cellular scale to the size of organs. Through a series of short talks the participants will present their work, where the workshop strives to stimulate scientific exchange and to initiate new collaborations.

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.​

NB! Coffee/Tea/Biscuits from 14.00.

The seminar in Mathematical Logic will take place in the meeting room of the Computer Science building Thursdays 10.15 - 12.00.

The purpose of the conference is to bring together leading researchers and students in stochastic analysis and applications, to discuss new results and research challenges, with emphasis on stochastic analysis, stochastic control and  information,  random fields, and applications to risk models in finance,  biology, insurance and physics.

Petter Nyland (NTNU) will give a talk titled: Matui’s Conjectures for Étale Groupoids.

M.Sc. Jonas Irgens Kylling ved Matematisk institutt vil forsvare sin avhandling for graden ph.d.
