We study certain 2 degree-of-freedom Hamiltonian systems arising from an approximation scheme for solutions of the 2d nonlinear Schrodinger equation with cubic-quintic or saturated nonlinearities (possibly in a grade-indexed medium). The solutions of these systems can be of various different … Continue reading Colloquium: Tuesday, December 1, 2pm. Speaker: Jeremy Schi ff (Bar-Ilan).
