Abstract:
Many complex systems in physics and
biology constitute networks of
dynamically interacting units. Examples
range from gene regulatory networks in
the cell and neural circuits in the brain,
to food webs in ecosystems and power
grids, as well as other supply systems
of engineering. Studying the interplay
between topology and dynamics in
such complex networks, and
specifically the study of how function or
dynamics constrain topology and vice
versa, is crucial for our ability to
understand, predict and control their
behavior. In this talk I will illustrate this
interplay by two examples:
1) The potential and characteristics of
information flow through different layers
of regulatory networks and the analysis
of shortest paths distributions in
configuration model networks
dominating such flow.
2) Revealing the topology of physical
interaction networks by exploiting
changes in invariant measures
generated by the system's collective
dynamics.
