Conferences and Summer Schools

The CRC recently held a summer school on wave phenomena in Karlsruhe bringing 53 participants from 12 countries around the world to Karlsruhe to focus on their shared interest in and faszination of wave phenomena. I personally recently took part in a conference in Italy (IMSE) leading some friends and family to ask me, what a conference or summer school amongst mathematicians is like. Since you might be thinking about a future in academic research yourself, while you read this, I want to take some time to tell you a little bit about what my experiences with these two formats have been and what they offer to you as a student or young researcher.

Harmonic Analysis at its Boundaries

In June 2016 we, Christine Grathwohl, Fabian Hornung and Luca Hornung, had the opportunity to participate in the summer school “Harmonic Analysis at its Boundaries” in Nantes. The aim of this event was to present recent advances in abstract and applied harmonic analysis in depth through three minicourses and to give an overview about connected topics through accompanying talks.

The origins of the harmonic analysis go back to the end of the 18th century. One of the founders of this theory was the French mathematician Joseph Fourier, who developed it during his attempts to solve differential equations. Nowadays applications are found in various fields of science and technology, reaching from acoustics and optics over signal processing till cryptography.

Consider for example a music song that you want to record as an MP3 file in such a way that you need as low memory capacity as possible. All the information on frequencies that are not in the frequency range that can be heard by us humans is not needed. It is impossible to delete this information directly from the signal caused by the air pressure in the microphone. Instead of this, one computes the Fourier transform of a signal that divides the information on the different frequencies. Now the very high and very low frequencies can be cut off easily and a retransform gives the desired result.

In the following, we want to give an insight into the topics of the minicourses mentioned above. A little cautionary reminder: this short report requires knowledge of some advanced mathematics.

CRC summer school on Wave Phenomena: analysis and numerics

version3_blogFrom 12th to 15th of September 2016 the CRC organized its first summer school on wave phenomena. It was directed to Ph.D. and advanced master students with a solid background in analysis and/or numerical analysis of partial differential equations. In the morning from Monday to Thursday two lecture series were held by  Herbert Koch (Bonn, Germany) and Alexander Ostermann (Innsbruck, Austria).

Grand opening of CRC 1173

Time flies – our CRC is now 15 months old, and a lot has happened since its beginning. In fact, there were so many activities that up to now we did not find time to celebrate the official beginning of our CRC. This was made good for by a two-day event on September 15-16, 2016. On the evening of the first day many PIs, doctoral students, summer-school participants and friends came to celebrate the official opening in the atrium of Department of Mathematics with a common dinner.

KIT‘s vice-president for research Prof. Oliver Kraft had accepted our invitation to join us for the grand opening.  After having worked his way through thick traffic on the A8-motorway he honored our CRC through his motivating and appreciative speech. Our CRC is very grateful for the ongoing support from him and the entire presidential committee of KIT. Continue Reading →

CISM summer school in Udine

Some persons claim that they are immune to advertising. We (that is Andreas Sturm, Jonas Köhler and David Hipp) can certainly not count us into that group of people: After multiple invitations over the central mailing list, we decided to participate in the CISM advanced school about ‘Computational Acoustics’  organized by Prof. Kaltenbacher (TU Wien) and sacrificed our Sunday and a holiday Thursday for the sake of scientific education.

CISM, International Centre for Mechanical Sciences, is a non-profit organization founded in 1968 and located in the beautiful and impressive Palazzo del Torso in Udine, Italy. The principal activity of CISM is the organization of courses, seminars, workshops and conferences to promote the exchange and application of advanced knowledge in mechanical science and in particular fields like robotics, biomechanics and environmental engineering.
