ABSTRACT:

The complexity of numerous social, biological or communication systems
originates in the network defined by the system's components and their
interactions.  The mathematical concept describing a network is a graph,
and traditionally complex networks have been described by the random graph
theory founded in 1959 by Paul Erdos and Alfred Renyi. But the emerging
results on real networks indicate that their topology is much richer than
that of random graphs.  In my talk I will review the established and the
emerging results in the theory and modeling of complex networks, focusing
on dynamical modeling as opposed to the traditional static approach.
Finally, I will discuss the response of complex networks to node
disruptions, and the effects of the network topology on the resilience of
the network.
