报告摘要:When the vorticity is monotone with depth, we present avariational formulation for steady periodic water waves of the equatorial flow in the $f$-plane approximation, and show that the governing equations for this motion can be obtained by studying variations of a suitable energy functional $\mathcal{H}$ in terms of the stream function and the theromcline. We derive criteria which ensure that the second variation of the constrained energy functional
is a nonnegative form, proving thus linear stability of steady
equatorial water waves with vorticity.
