Abstract.

We consider the Zakharov system, coupling Schr\"odinger-like and wave equations, which models some dynamics in a plasma. This system in its physical derivation depends on a parameter $\alpha$ describing the temperature of this plasma. Large value of such parameter describes a plasma which is not very hot, so is meaningful to study the limit for $\alpha$ towards infinity as physical observations suggest. In this talk we prove rigorous mathematical result in this direction. (Joint work with Paolo Antonelli, GSSI, L’Aquila)
