Here are some things you might want to know about...

Every homepage needs a section where visitors can find information about the author. After all, this is Web 2.0. Below are some pictures of me, including a recent portrait and a somewhat more artistic depiction of me receiving the official geek distress signal while lurking over the rooftops as a software vigilante. The red hat does not indicate a preferred Linux distribution.

Who am I?

  • I have a personal homepage. You are visiting it at the moment.
  • On this homepage, I have a blog, whose posts are mostly quick notes about things I don’t want to forget.
  • I have a profile on ResearchGate for collecting publications and simplifying academic exchanges. I used to have a profile on, but found ResearchGate to be more relevant.
  • I also have a Google+ profile, but I mainly use it as an outlet to write about the posts that appear in my blog.
  • I have a Twitter account although I don’t even know how this Twitter thing is supposed to work.

Note that you won’t find me on Facebook, because I very much dislike it. Since my name is not that unique, Facebook profiles of Bastian Rieck might exist, but I am not affiliated with any of them. Unfortunately, as this article shows, Facebook will probably have some information about me anyway. Well, I tried.

A more concise description of my (professional) life so far can be obtained from reading my curriculum vitæ. A more entertaining read is my geekcode:

See what some random tests say about me:

If I were a Springer-Verlag Graduate Text in Mathematics, I would be Bela Bollobas’s Modern Graph Theory.

I am an in-depth account of graph theory, written with the student in mind; I reflect the current state of the subject and emphasize connections with other branches of pure mathematics. Recognizing that graph theory is one of several courses competing for the attention of a student, I contain extensive descriptive passages designed to convey the flavor of the subject and to arouse interest.

I have used the excellent ikiwiki wiki compiler to create most of these pages. The original content has been ported from static HTML pages.

The site is hosted on a virtual server by DigitalOcean. So far, I am quite satisfied with the quality of their services.

Some of these days, I’ll add more content to this section. In the meantime, enjoy a list of broken links in the wiki:
