Recall that the linearization (a linear system) has an isolated critical point at the origin if and only if both of its eigenvalues are non-zero.

But how should I determine if it's "left-handed" or "right-handed" spiral, or which way the centre is turning? ordinary-differential-equations nonlinear-system Share
WebNonlinear processes in systems with many degrees of freedom, including phase change in condensed matter, proceed via initial fluctuations in the starting state. Many fluctuations are transitory and leave the state unchanged, but some, sufficiently strong in some required sense, carry the system into a different one. WebIn this work, the classic problem of the aeroacoustic instability occurring in deep cavities subject to a low-Mach grazing flow is revisited experimentally and theoretically. This instability is caused by the constructive feedback between the acoustic modes of the cavity and the turbulent shear layer that forms at its opening. Systematic experiments are …
