Four SFB members, Otmar Scherzer, Ronny Ramlau, Ekaterina Sherina and Denise Schmutz (pictured) attended the Oberwolfach workshop on ‘Tomographic Inverse Problems: Mathematical Challenges and Novel Applications’ between 30 April and 5 May, 2023. Denise Schmutz also received the Oberwolfach Leibniz Graduate Student Grant.
SFB Speaker Otmar Scherzer gave a talk on Newton methods for solving linear inverse problems with neural network coders at a colloquium in Linz which celebrated the 20th anniversary of the Johann Radon Instute (RICAM) and the 70th birthday of its founder, Prof. Heinz W. Engl.
Prof. Heinz W. Engl also gave an interview in which he was asked about how research has developed since his inception of the institute and what his own personal research highlights are, the transcript for which may be found here.
The 13th Internal SFB Meeting took place between 12-15 February in Villa Sonnwend, Roßleiten, Austria. It was an action-packed event featuring notable talks from members, as well as memorable debuts from external and international participants from realms as far flung as Finland.
In addition to the talks, there was a free afternoon on Tuesday 14 February which coincided with Valentine’s Day.
The Special Semester on “Tomography Across the Scales” concluded with its final workshop on “Inverse Problems in Large Scales” and spanned the interval between 28 November – 2 December 2022.
There, SFB member Fabian Hinterer gave a talk on “a projected Nesterov-Kaczmarz approach to stellar population distribution reconstruction in Extragalactic Archaeology” in the presence of experts spanning the various mathematical branches that are connected to inverse problems. Other SFB members were also participants, including organisers Otmar Scherzer and Ronny Ramlau, as well as Peter Elbau, Michael Quellmalz, Ekaterina Sherina, Simon Hubmer and Kemal Raik.
We would once again like to thank the organisers for their hospitality and providing the platform for experts in the area to share and exchange ideas.
From 10th to 21st of October, the first two workshop-weeks of the RICAM Special Semester “Tomography across the Scales” took place at the Johann Radon Institute for Computational and Applied Mathematics in Linz. There, Fabian Hinterer, Simon Hubmer, Michael Quellmalz, Ekaterina Sherina and Leopold Veselka, all members of the mathematical subprojects within the SFB project, were invited to present their latest scientific advances to an audience of experts in the various fields of Inverse Problems.
Furthermore, the members got the chance to exchange ideas with other researchers and to benefit from external input.
We express our gratitude to the organizers for the invitation and the hospitality during these perfectly organized workshops!
Currently, the autumn school as part of the Special Semester “Tomography Across the Scales” takes places at the RICAM in Linz. Peter Elbau, one of our project leaders, was invited to give an introductory lecture on the mathematics behind optical coherence tomography. The audience, including several members of SFB, warmly welcomed the intuitive and very well presented lecture on this highly complex topic.
From June 19 to 22, 2022, for the first time new and old members of the SFB project “Tomography Across the Scales” met each other in person in Roßleithen(Upper Austria). Interesting talks about the already accomplished and the possible future work helped the new members to get to know the various fields of research and initiated discussions about additional collaborations within the SFB project.
A hiking trip up to the Wurbauerkogel concluded this well organized event.
The online Workshop at the Erwin Schrödinger International Institute for Mathematics and Physics (ESI) has just started. This is a two-weeks event with more than 50 international researchers participating.
In the first week (March, 15th – 18th), we have mainly talks from applied mathematicians presenting results on tomographic reconstructions while the second week (March, 23th – 25th) covers the practical applications of such methods in astronomy and medical imaging. See the full program here.
Registration is free. You just have to contact Peter Elbau.
The Tenth International Conference “Inverse Problems: Modeling and Simulation” (IPMS2021) has now been postponed to May 22 –28, 2022. The conference takes place in Malta.
We are happy to announce that we are organizing a mini-symposium entitled “Mathematical Methods in Tomography Across the Scales” related to our SFB. The speakers are members and associated members of the SFB.
See more about this mini-symposium!
The 6th Internal Meeting took place virtually on November 30th and December 1st. Unfortunately, we could not meet in person due to the current circumstances but this online meeting gave us the opportunity to be all together in an online room.
In this meeting, very interesting talks were presented from our members and associate members of the SFB. The principal investigators presented the current status of research and future plans. Gabriele Steidl (TU Berlin, Germany) and Glenn van de Ven (University of Vienna) presented their research interests and ideas for future collaborations within the SFB.
Hopefully we can meet in person again in Obergurgl in March!
