About the event
Abstract/Synopsis: Over the past 150 years, we have built up really good understanding of how individual sub-systems behave. As we connect more and more “things” and “people” together through digital and mechanical technology, we must ask how network topology affects their performance and resilience. This problem is challenging when the size of the network becomes large and run away cascades can cause regional to national scale catastrophes. Here, we offer some initial research into finding the specific relationship between networked dynamics (stability, rate of convergence) and the network topology (eigenvalue, degree). We showcase results for both natural ecosystems and built infrastructures, ranging from water distribution, to transport, to telecommunications. We also point towards methods to reconfigure the topology in a way that stabilises the system, but highlight a regulatory paradox.
