Global mode
text:
In the physics of hydrodynamics, a global mode of a system is one in which the system executes coherent oscillations in time. Suppose a quantity y which depends on space x and time t is governed by some partial differential equation which does not have an explicit dependence on t. Then a global mode is a solution of this PDE of the form y = y ^ e i ω t, for some frequency ω. If ω is complex, then the imaginary part corresponds to the mode exhibiting exponential growth or exponential decay. The c
