Abstract
Drift vortices are described by the Hasegawa–Mima equation in the case of density gradient drift waves. From computer results, it is known that the modon solutions of the Hasegawa–Mima equation are quite stable. Here the linear stability of ground state modon solutions is proved analytically by an indirect technique.Keywords
