Haakon Bakka (formerly Computer Electrical Mathematical Science and Engineering Division, King Abdullah University of Science and Technology, KSA, from 01.02.2020 Department of Mathematics, University of Oslo) will give a talk on February 25th at 14:15 in the Erling Sverdrups plass, Niels Henrik Abels hus, 8th floor.

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.

Morten Hjorth-Jensen (Department of Physics, University of Oslo and Department of Physics and Astronomy, Michigan State University, USA) will give a talk on March 3rd at 14:15 in the Erling Sverdrups plass, Niels Henrik Abels hus, 8th floor.

Lokukaluge Prasad Perera (Department of Technology and Safety, Artic University of Norway) will give a talk on March 16th at 14:15 in the Erling Sverdrups plass, Niels Henrik Abels hus, 8th floor.

Dr. Carlo Sgarra from Politecnico Milano will give a Seminar Lecture: A Gamma Ornstein-Uhlenbeck Model Driven by a Hawkes Process

A conference in honour of Nils Henrik Risebro on the occasion of his 60th birthday.

The 5th Scandinavian Gathering Around Remarkable Discrete Mathematics

We invite you to a two-day seminar celebrating Professor Ørnulf Borgans many and substantial contributions to statistics in general and life event history analysis in particular. The seminar takes place in Auditorium 2 in Helga Engs House, Blindern Campus, University of Oslo, from Monday May 25th 11:00 to Tuesday May 26th, 14:00, 2020.

For the seminar we have invited several of Ørnulf's key collaborators to give talks. We hope many other colleagues, students and friends will participate in this celebration of Ørnulf and his outstanding career as Professor of Statistics at the University of Oslo.

The conference is part of a joint French-Norwegian conference series on curves and surfaces. In Norway previous meetings were held in Oslo 1988, Biri 1991, Ulvik 1994, Lillehammer 1997, Oslo 2000, Tromsø 2004, Tønsberg 2008, Oslo 2012, and Tønsberg 2016. In France the last meeting was in Arcachon 2018.

The format of the conference is informal and invites discussion of ideas and work in progress.

On 7-9 September 2020, the conference on high-dimensional stochastics will take place 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.  

A pre-conference PhD course will be organized on Monday September 7. The course is related to the topics of the conference and will be given by Christa Cuchiero.  More details on the course will be announced soon.
