Abstract

In this paper, we continue our investigation of the relation between various systems that can be derived from the Klein-Gordon-Zakharov system in the high-frequency and subsonic limits. In this paper we start from the singular nonlinear Schr\"odinger system which was derived in a previous work and derive the classical nonlinear Schr\"odinger system in two different limit cases. These two nonlinear Schr\"odinger systems have different coefficients in the nonlinearity
