Interns at the Institute of Mathematics

Five interns spent 4 weeks with us at the Institute of Mathematics.  And they did a really great job under the guidance of Benjamin Hackl and Roswitha Rissner. The explanatory videos they produced are online at

The man who calculates the future

Under which conditions can mathematics be used to calculate how many and which animals will live where, how viruses will spread, and how strong our economic performance will be tomorrow? Christian Aarset has developed mathematical models that allow us to calculate the future. He recently completed his doctoral thesis under the supervision of Christian Pötzsche.

Remarkable success for Mathematics and Statistics at the University of Klagenfurt: funding for 14 new PhD students in the field of optimization in FWF doc.funds project

The approval of this project represents a milestone in the success story of the Departments of Mathematics and Statistics at the University of Klagenfurt. It’s also a great achievement on the part of the participating professors and particularly for the 32-year-old coordinator, Michaela Szölgyenyi. Starting in autumn 2020, the project will employ around one dozen international young scientists in Klagenfurt.

Mathematics supports new medical imaging techniques

While MRI, CT and x-ray already provide valuable insights into the interior of the body, the technology involving so-called magnetic particle imaging now promises new possibilities with high resolution, less acquisition time and no harmful radiation. In order to be able to draw conclusions about biological processes based on the observation of magnetic particles in a magnetic field, research has to rely on mathematics. Tram Thi Ngoc Nguyen is completing her doctoral thesis on this topic at the University of Klagenfurt.

Daniel Krenn and Annika Wille received their habilitation certificate

This year, two colleagues at our faculty defended successfully their habilitation thesis. Daniel Krenn, Department of Mathematics, received the venia docendi in Mathematics, and Annika Wille, Department of Mathematics Education, the venia docendi for Mathematics Education. The certificate was presented on June 17 by the Dean Gerhard Friedrich and the Vice Dean Clemens Heuberger.

Congratulations to our young colleagues for their excellent work and contributions to the field of Mathematics and Mathematics education!

Habilitation colloquium of Daniel Krenn

On January 25, 2019, the habilitation colloquium of Daniel Krenn took place. The talk titled

“Research in the spirit of analytic combinatorics explained on the example ʽQuicksort algorithmʼ”

revealed Daniel’s research endeavour and showed his technical proficiency and scientific maturity.

Daniel managed to explain key issues of his research so that it was accessible to the general audience, and at the same time he impressed the experts by his highly nontrivial and interesting work. The presentation was followed by a vivid discussion which covered theoretical issues along with algorithmic aspects all the way to purely didactical questions, for instance how to communicate complicated mathematical topics to children.

We wish Daniel Krenn all the best and many more results that advance the state-of-the-art in Analysis of Algorithms and Analytic Combinatorics!

Using mathematics to improve rail cargo planning

Every year, around 8,400 employees transport more than 100 million tonnes of goods on behalf of Rail Cargo Austria. 620 traction units and 21,500 goods wagons are required purely for rail cargo operations. In the case of highly complex logistics tasks such as this, the deployment of man and machine requires careful planning. Mathematicians working on a project funded by FFG are now developing algorithms designed to significantly enhance the planning process.

The AAU Delegation to the European Women in Mathematics General Meeting 2018

The European Women in Mathematics association (EWM) held its general meeting at the Institute for Mathematics of the Karl Franzens University Graz during September 3-7, 2018, celebrating 30 years of existence. The conference was co-organised by Elena Resmerita (Institute for Mathematics of the AAU), who was re-elected as deputy convenor for the period 2018-2020 together with Carola Schönlieb (Cambridge University) as an EWM convenor. More than one hundred female mathematicians from all over Europe met for excellent scientific lectures, minisymposia and posters presentations, discussions and networking:

Laurenz Kohlbach qualifies again for the International Mathematical Olympiad

Laurenz Kohlbach (Stiftsgymnasium St. Paul) has attended the course of Mathematical Olympiad of the Alpen-Adria-University Klagenfurt for several years now. This year he again qualified for the International Mathematical Olympiad, which takes place in Romania this year.


He has mastered the way there brilliantly. After winning the first prize in the regional competition for advanced students, he solved all problems and got the first place in the first part of the national competition. He also won the first place in the second part of the national competition (two days on May 31 and June 1) together with Veronika Schreitter. This year’s International Mathematical Olympiad will take place from July 3 to 14 in Cluj-Napoca, Romania. There Laurenz Kohlbach and 5 other Austrians will compete for medals.


Laurenz Kohlbach already took part in the International Mathematical Olympiad in Brazil last year and received a silver medal there.

14th Austrian Numerical Analysis Day 2018

On May 3 and 4, the 14th ANADay took place at the AAU, organized by Barbara Kaltenbacher und Elena Resmerita (Institut für Mathematik, Alpen-Adria-Universität Klagenfurt) as well as Mechthild Thalhammer (Institut für Mathematik, Leopold–Franzens Universität Innsbruck).

The aim of this annual workshop is to inform about activities in the fields of numerical analysis and applied mathematics. Scientists from Austrian universities and other research institutions in particular present their research, exchange ideas, and start new collaborations. With more than 70 participants, this year’s workshop was very successful.
