Hamiltonian form of extended cubic-quintic nonlinear Schrödinger equation in a nonlinear Klein-Gordon model
Yu. V. Sedletsky, I. S. Gandzha
We derive an extended cubic-quintic nonlinear Schrödinger equation with Hamiltonian structure in a nonlinear Klein-Gordon model with cubic-quintic nonlinearity. We use the nonlinea…

Epidemic-Driven Collapse in a System with Limited Economic Resource. II
I. S. Gandzha, O. V. Kliushnichenko, S. P. Lukyanets
We consider a possibility of socioeconomic collapse caused by the spread of epidemic. To this end, we exploit a simple SIS-like (susceptible-infected-susceptible) model with negati…
