Chun-Hung Liu (劉俊宏), Asymptotic dimension of minor-closed families and beyond
Zoom ID:95464969835 (356260)The asymptotic dimension of metric spaces is an important notion in geometric group theory. The metric spaces considered in this talk are the ones whose underlying spaces are the vertex-sets of (edge-)weighted graphs and whose metrics are the distance functions in weighted graphs. A standard compactness argument shows that it suffices to consider the asymptotic …
