General Information


Graphs and networks model realworld situations and often the graph defining structures are geometric. This makes a tailored treatment of geometrically defined graph classes an important branch of research, both theoretically and practically. For example, road networks give rise to almost planar graphs, job schedules give rise to intersection graphs of intervals, or DNA sequences give rise to graphs with a linear ordering on their vertices. On the other hand, geometry can be intentionally inferred to graphs for visualization purposes.

In this seminar, we discuss a wide range of geometric settings for graphs and combinatorial problems. Topics include among others the existential theory of the reals, VC-dimension, machine learning, planarization, and visualization.


At the first, preliminary meeting, the topics will be briefly presented and assigned to the participants. Afterwards each participant explores their topic using the given literature as a starting point. After a couple of weeks each participant gives a 5-minute short presentation on their topic. During the semester we will then have the main presentations on separate days. By the end of the semester and after a peer review phase, each participant has to hand in a written report of 12–15 pages in LaTeX. The overall grade depends equally on the main presentation and the written report.

Guidelines can be found in the introductory slides .
