Dear colleagues,

We are happy to announce the following online talk:

Speaker: Michele Salvi (Università di Roma "Tor Vergata")

Title: Scale-free percolation mixing time.

Abstract: Scale-free percolation is a spatial inhomogeneous random graph
model which features three fundamental properties that are often present
in real-world networks: (1) Scale-free: the degree of the nodes follows
a power law; (2) Small-world: two far-away nodes have typically a small
graph distance; (3) Positive clustering coefficient: two nodes with a
common neighbour have a good chance to be linked. We study the mixing
time of the simple random walk on this structure in one dimension and
depict a rich phase diagram in the parameters of the model. In
particular, we prove that the presence of hubs can speed up the mixing
of the chain. Joint work with Alessandra Cipriani (UCL).

Date and time: Monday May 9, 17:30-18:30 (Rome time zone)
