When a rubber tube is inflated, it will first expand uniformly, and then at a critical pressure it will suffer localized bulging. However, it is known that human arteries will not suffer localized bulging (aneurysms) unless some pathological changes have taken place. A natural question to ask is “what is the design principle for human arteries”. Although localized bulging has been studied since 1891 both theoretically, numerically and experimentally, it is only in the recent decade that localized bulging has been investigated systematically as a bifurcation phenomenon. It is under this new framework that the above question could be addressed as a mathematical question. At the seminar, I will report on the most recent developments.
