The model proposed makes several assumptions. My question is about: Many real-world networks are heterogeneous and as such are expected to undergo large-scale cascades if some vital nodes are attacked. on page 3. I do not get the basis for this assumption. So any help for a 60's educated math major would be appreciated. On Thu, 6 Feb 2003 sgorman1@gmu.edu wrote:

Sigh, there are differences between tightly coupled networks, such as the electric power grid and loosely couple networks like the
But there are also some similarities, such as electric grids use DC interconnections to limit how far AC disturbances propagate; the Internet uses AS interconnections to limit IGP disturbances from propagating.
