Welcome to my technical blog!

On this site, I will post a loose collection of small articles that, in my estimation, are not sufficiently substantial to deserve publication as full paper or talk, nor deserve a separate Git repository of their own, but still would make me sad, if deposited onto the dump of forgetting. This blog also ingests tools and techniques such that parts of this material may make their way into future papers or talks one way or another.

Just think of Fermat’s Last Theorem. He had in mind a proof for the assumption that no three positive integers \(a\), \(b\), and \(c\) satisfy the equation \(a^n + b^n = c^n\) for any integer value of \(n\) greater than 2, but did not have enough space to scribble it down in the margin of a copy of the Ancient Greek text Arithmetica. Still, he obviously considered his proof not being sufficiently important to be published elsewhere, such that, very sadly, we do not know anything even about just his idea for a proof, regardless whether it did work or not. Actually, most likely, he was wrong in believing he could prove his theorem just in a little bit more of space. Finally, more than 300 years later, Fermat’s theorem itself proved to be right, though requiring a highly complex proof. If Fermat only had kept a blog, he could have published there at least his idea for a proof.

In fact, there are often ideas by far not as relevant as Fermat’s comment, that, at first sight, do not seem being worth to be worked out in full detail, or corollaries, or even findings from meanders and dead ends, but which may be still in general interesting to know, as they may contain enlightning insights into the overall topic. Some authors use the opportunity of writing textbooks to utilize bycatch insights as inspiration for creating excercises for students for further elaboration. Since I am currently not writing any textbook, I use this blog instead as an abode for otherwise homeless knowledge.

I reserve the right to subsequently make changes such as minor corrections or additions to existing blog posts. If you want to track the full history of a specific blog post, you may look into its revision history in the associated Git repository, that holds the source files of this blog.
