Received May 29, 2026.   Published online November 11, 2026.   OPEN ACCESS

Abstract:  This work deals with the ergodicity of the stochastic dissipative Hasegawa-Mima equations in a bounded domain driven by additive noise. The uniqueness of the invariant measure is obtained by the asymptotic coupling technique.
Keywords:  plasma physics; magnetohydrodynamics; invariant measure; ergodicity
