Today I gave a talk (actually, the first of two parts) in Mark Ward‘s informal seminar on Analytic Combinatorics at Purdue University. The abstract and additional resources can be found below.

Es war mir eine besondere Freude, heute in meiner ehemaligen Schule, dem BRG Viktring, einen Vortrag aus Mathematik vor den 7. Klassen halten zu dürfen.

Today I held an invited workshop on combinatorics and the symbolic method at the Mathematical Institute of Bonn University (Bonn, Germany) for alumni who received a “Hans-Riegel-Fachpreis“, a flyer for this event can be found here. The (german) slides and corresponding exercises can be found here (lecture slides) and here (exercises).

This was a great opportunity, and I enjoyed holding the workshop a lot. 🙂

I made a submission to Insight2016, which is an exhibition dedicated to the visualization of (scientific) data, taking place in Lakeside Science & Technology Park, Lakeside B11, 9020 Klagenfurt am Wörthersee, Austria, in April and May, 2016.

The picture I submitted is called Climbing Densities, and looks like this:

Essentially, these are probability densities of a sequence of random variables I’m currently researching. These random variables model some parameter of a combinatorial object for fixed size. The more intensely colored densities represent larger object, so what can be observed is some sort of periodic process, which is also visualized in this gif (1 density per frame):

More information on these combinatorial object will appear in an upcoming paper (joint work with Helmut Prodinger).
