Representation of the theoretical behaviour of Nonlinear Schroedinger equation (representing amplitude of pulsed lasers in optical fibres, for example) near the ``gradient catastrophe''. The maximal gain of the chirps relative to the background is 3. This also is used to describe qualitatively the occurrence of solitary "monster waves" in the ocean.

M. Bertola, A. Tovbis, ”Universality for the focusing nonlinear Schrödinger equation at the gradient catastrophe point: rational breathers and poles of the Tritronquée solution to Painlevé I ”, Comm. Pure Appl. Math. 66 (2013) no.5, 678–752. doi:10.1002/cpa.21445

The dots are the (very regular) pattern of zeros of a "generalized Vorob'ev Yablonski polynomial" and also represents the set of poles of a special rational solution of the second Painlevé hierarchy of equations. The triangular array of dots near the corners is related to the position of the spikes in the other figure.

Amplitude of the quasi-periodic structures in certain solution of the Nonlinear Schrödinger equations, used in modelling rogue waves.
