A Report from Uppsala
It’s time for an update! A lot of stuff has happened in the past few weeks, and I think my blog is a good space to keep track of it all (at least a bit 😅).
Mathematician tackles Austrian school leaving exam: BHS edition
After a lot of positive feedback for my video regarding the school leaving exam, I decided to do the same thing for the school leaving exam in mathematics for a different Austrian school type (BHS).
Mathematician tackles Austrian school leaving exam
As there was some controversy regarding the difficulty of the Austrian school leaving exam in mathematics, I got interested and wanted to check things out for myself.
Technology for Online Teaching during Social Distancing
For some reason, my students this semester are happy with what I have done to move my classes to online formats (which, of course, was neccessary due to COVID-19). A friend asked me to write an article containing my views and recommendations for online teaching for a magazine, resulting in the text below. The article did not appear yet – but as soon as it does, I’ll update this blog entry with a link to it.
Workshops @ BRG Viktring: Von Büchern, Tauben und den Türmen von Hanoi
Es war mir eine große Freude, wieder einmal in meine alte Schule, dem Bundesrealgymnasium Klagenfurt-Viktring zurückzukehren um Mathematik-Workshops mit allen siebenten Klassen abzuhalten.
Goodbye Wordpress, Hello Jekyll!
I am currently in the process of migrating my old Wordpress site to a collection of static pages, generated by Jekyll. I am migrating because of the following reasons:
Schulvortrag @ BRG Viktring
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.
Talk @ ANALCO17: Iterative Cutting and Pruning of Planar Trees
I gave a talk at the 2017 Meeting on Analytic Algorithmics and Combinatorics (ANALCO17).
Talk @ AEC2016: On Reductions of Rooted Plane Trees
Today I gave a talk at AEC Summerschool 2016 at JKU’s Research Institute for Symbolic Computation (RISC) in Hagenberg, Austria.
Talk @ AofA16: The Register Function and Reductions of Binary Trees and Lattice Paths
On July 8, I gave a contributed talk 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.
Talk: On a Reduction of Lattice Paths
Today I gave a talk at Stellenbosch University (South Africa) presenting my current research on a reduction procedure for two-dimensional lattice paths consisting of the four steps up, right, down, left.
Jupyterhub with SageMath Kernel
Recently I made some efforts to get a Jupyterhub instance with a SageMath kernel up and running on one of my servers — with success! 🙂 Actually, the installation is really not that difficult. Nevertheless, I want to write a few lines describing the troubles I ran into and my solutions.
Asymptotic Expressions: Current Developments
Since my last blog entry on the status of our implementation of Asymptotic Expressions in SageMath quite a lot of improvements have happened. Essentially, all the pieces required in order to have a basic working implementation of multivariate asymptotics are there. The remaining tasks within my Google Summer of Code project are:
House(s) of Cards
When I sat at our family dinner on Saturday, I watched my cousin build a house of cards from coasters. At one point he said to me: “I want to build a reeeally tall house of cards. One with like 100 levels! Do you think we could collect enough coasters from the tables around here?”. The question got me interested, and so I decided to do some counting.
Asymptotic Expressions: Motivation
So, as Google Summer of Code started on Monday, May 25th it is time to give a proper motivation for the project I have proposed. The working title of my project is (Multivariate) Asymptotic Expressions, and its overall goal is to bring asymptotic expressions to SageMath.
Google Summer of Code — Countdown
Today I received the welcome package for attending this year’s “Google Summer of Code”! Actually, it’s pretty cool; the following things were included:
