Modulation approximation for the non-isentropic Euler-Poisson system
Huimin Liu, Xueke Pu
As a formal approximation, the nonlinear Schrödinger (NLS) equation can be derived to describe the evolution of the envelopes of small oscillating wave packets-like solutions to t…

The bidirectional NLS approximation for the one-dimensional Euler-Poisson system
Huimin Liu, Yurui Lu, Xueke Pu
The nonlinear Schrödinger (NLS) equation is known as a universal equation describing the evolution of the envelopes of slowly modulated spatially and temporarily oscillating wave…
