Energy convergence for singular limits of Zakharov type systems

Nader Masmoudi, Kenji Nakanishi

Research output: Contribution to journalArticlepeer-review


We prove existence and uniqueness of solutions to the Klein-Gordon-Zakharov system in the energy space H 1×L 2 on some time interval which is uniform with respect to two large parameters c and α. These two parameters correspond to the plasma frequency and the sound speed. In the simultaneous high-frequency and subsonic limit, we recover the nonlinear Schrödinger system at the limit. We are also able to say more when we take the limits separately.
