Abstract:
Systems as diverse as the world wide web or the cell are described by
networks with complex topology. Traditionally it has been assumed that
these networks are random. However, recent studies indicate that such 
complex networks are the result of self-organizing processes governed 
by simple but generic laws, resulting in topologies strikingly different
from those predicted by random networks. I will discuss the implications 
of these findings on the error and attack tolerance of the Internet, the
robustness of the cells, and other properties of complex evolving 
networks.
