The aim of this work is to establish, from a mathematical point of view, the limit α → +∞ in the system where . This corresponds to an approximation which is made in the context of Langmuir turbulence in plasma Physics. The -subcritical (that is 2/3) and the -subcritical (that is 2) are studied. In the physical case = 1, the limit is then studied for the norm.
