Fragility in Large-scale Dynamics: From Shear-flow transition to Anderson Localization to Networked Dynamical Systems
Reception following! Abstract
Some mathematical models of physical phenomena can exhibit radically different behavior when modified slightly to account for additional physical mechanisms. This can be understood as fragility of the mathematical model to small "perturbations" in the dynamical description. These phenomena appear to be more ubiquitous than is generally believed. Hydrodynamic stability of wall-bounded shear flows is one striking example where flow fluctuations are highly susceptible to even small irregularities. The well-known phenomenon of Anderson localization is another one where small amounts of material disorder can radically alter the nature of dynamical modes. Recent work has shown that such localization phenomena can also occur without the presence of medium disorder, but rather due to complex geometry such as in…
