What is it about?
In a layered dynamical systems, noise is transmitted from one layer to the other with system-specific correlation in space and time. Such correlations have the potential to strongly amplify the fluctuations in the connected layers. Moreover, fluctuations are amplified along some favored directions. In this article I show that both the increased amplitude and the particular directions of the fluctuations seem to lead to shorter first escape times from the initial basin of attraction.

Why is it important?
These results highlight the vulnerabilities of dynamical systems made of multiple layers of networked units.
