DESCRIPTION:Date: \n\n2:30pm to 3:30pm\n\n\n\n\nSee also: Events & Semina
rs\, Colloquium\n\n\nA finite graph is automatically also a metric space\,
but is there any interesting geometry to speak of? In this lecture I will
try to convey the idea that indeed there is very interesting geometry to
explore here. I will say something on the local side of this as well as on
the global aspects. The k-local profile of a big graph G is the following
distribution. You sample uniformly at random k vertices in G and observe
the subgraph that they span. Question - which distributions can occur? We
know some of the answer but by and large it is very open. In the global pa
rt I concentrate on the question “to what extent can a finite d-regular gr
aph resemble the infinite d-regular tree”? I will show how this naive-soun
ding question leads to very difficult and fascinating problems about girth
and diameter of large graphs.\nThe lecture will be completely elementary
and should be accessible to a broad mathematical audience.\n\n Export\n
