Schulvortrag @ BRG Viktring

By behackl,

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.

Die Vortragsfolien sind hier zu finden.

Summer school: Techniques in Random Discrete Structures

By behackl,

I’m currently in Athens at the summer school “Techniques in Random Discrete Structures”, where I am responsible for the exercise sessions.

An overview over which exercises have already been dealt with, can be found here.

The current versions of the three exercise sheets are available here:

  • Exercises to Phase transitions in random structures (Amin Coja-Oghlan, Frankfurt)
  • Exercises to Gibbs measures in statistical physics and combinatorics (Will Perkins, Birmingham)
  • Exercises to Analytic Combinatorics (Stephan Wagner, Stellenbosch)

Mathematik-Seminar der Hans-Riegel-Stiftung

By behackl,

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. 🙂



The Register Function and Reductions of Binary Trees and Lattice Paths — AofA’16

By behackl,

On July 8 I gave a contributed talk on “The Register Function and Reductions of Binary Trees and Lattice Paths” at this years 27th edition of the International Conference on Probabilistic, Combinatorial and Asymptotic Methods for the Analysis of Algorithms (AofA’16), which took place in Kraków, Poland.

My Slides can be found here.


Submission to Insight2016

By behackl,

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).
