C*-algebra seminar talk by Ole Brevig (University of Oslo)

Time and place: , Niels Henrik Abels hus, 9th floor, seminar room 919

DuMux  (short for "Dune for Multi- {Phase, Component, Scale, Physics,…} flow and transport in porous media") is  a free and open-source simulator for flow and transport processes in porous media. DuMux is modern C++ code based on the scientific software framework Dune (Distributed and Unified Numerics Environment) and has a focus on modularity and reusability. 

The main features and ideas behind DuMux will be introduced with several examples from recent research projects.

This talk is part of the Mechanics Lunch Seminar series. That means 20min talks plus discussion in an informal setting.

Time and place: , Wolfgang Pauli Institute, Vienna

On 7-9 September 2020, the conference on high-dimensional stochastics will take placeas a virtual meeting under the auspices of at the Wolfgang Pauli Institute (WPI) in Vienna, Austria. The conference is an activity within the thematic program "Mathematics for Risk in Finance and Energy" at the WPI. 

We aim to bring together an interdisciplinary group of leading researchers with interest in high dimensional stochastic modeling. Particular emphasis will be given to infinite dimensional Markov processes, SPDEs, population dynamics, high dimensional statistics and connections to financial and energy modeling. We welcome participants from academia and industry to take part in this event.

The 5th Scandinavian Gathering Around Remarkable Discrete Mathematics

Time and place: , Online

During these strange corona times, the need for continuous interaction in science is coming stronger.

We now launch this new Spring Seminar Series Online in probability, stochastic analysis and applications. 

These online seminars are both meant to give a scientific update of our doings, as well as being a social event that we can attend once a week from our home-office. Prepare yourself with a good cup of coffee or tea!

If you want to take part to the seminars, please register at this link.

              Connes isometries of the Cuntz algebras

Time and place: , Rest area, 10th floor NHA

 

In my talk I will discuss the use of topological methods in the analysis of neural data. The key idea is to associate a space to the data set and then determine its shape by using persistent homology. In this way we have obtained good state spaces for Head Direction Cells and Grid Cells. Topological decoding shows how neural firing patterns determine behaviour.This is an interesting local to global situation which gives rise to some reflections. Based on very recent experimental results from the Moser-Lab at NTNU we show that the state space of a population of grid cells is a two dimensional torus!

Abstract:

In 1823 Niels Henrik Abel published a paper with title "Oplösning af et par opgaver ved hjelp af bestemte integraler," (Solution of a couple of problems by means of definite integrals), Magazin for Naturviden-skaberne, Aargang I, Bind 2, Christiania, which did not appear in French translation until 1881. Here he presented a complete framework for fractional-order calculus with appropriate notation for non-integer-order integration and differentiation. This seems to have been unknown until discussed in Podlubny, Magin, Trymorush, "Niels Henrik Abel and the birth of fractional calculus," Fractional Calculus and Applied Analysis, pp. 1068-1075, 2017.

I will give an introduction to non-integer order calculus and Abel's derivation of it. This will be done by going through his 1823 paper showing how he assumes a generalization of both Cauchy's formula for repeated integration and the fundamental theorem of calculus. In addition I will show how fractional calculus can be used to derive fractional-order partial differential wave equations. They have solutions with power-law attenuation which matches measurements in the complex media of medical ultrasound and elastography as well as in sediment acoustics and seismics.
