On July 1, 2025, Sergey Norin from McGill University gave a talk at the Discrete Math Seminar on the asymptotic dimension of intersection graphs. The title of his talk was “Asymptotic dimension of intersection graphs“.
The notion of asymptotic dimension of metric spaces, introduced by Gromov, describes their large-scale behaviour. Asymptotic dimension of graph families has been recently studied, in particular, by Bonamy et al. who proved that the asymptotic dimension of proper minor-closed graph families is at most two.
We will discuss nerve-type theorems for asymptotic dimension. In particular, we show that the asymptotic dimension of intersection graphs of balls and spheres in
