Amplitude and phase of time dependent Hamiltonian systems under the minimum uncertainty condition
G. Landolfi, G. Ruggeri, G. Soliani
We investigate dynamical systems with time-dependent mass and frequency, with particular attention on models attaining the minimum value of uncertainty formula. A criterium of mini…

Induced surfaces and their integrable dynamics. II. Generalized Weierstrass representations in 4D spaces and deformations via DS hierarchy
B. G. Konopelchenko, G. Landolfi
Extensions of the generalized Weierstrass representation to generic surfaces in 4D Euclidean and pseudo-Euclidean spaces are given. Geometric characteristics of surfaces are calcul…
