Radiation and dissipation of internal waves generated by geostrophic motions impinging on small-scale topography
… motions flowing over bottom topography. Weakly-nonlinear theory is used to describe the internal wave generation and the feedback of the waves on the zonally averaged flow. A major finding is that the waves generated at the ocean bottom at finite inverse Froude numbers drive vigorous …

Shear flow instabilities in stratified magnetohydrodynamics
… towards the astrophysically relevant case. Using weakly nonlinear theory, we derive amplitude equations for the two cases of Pe,Rm∼O(1) and Pe,Rm»1, where Pe (the ratio between thermal convection and thermal diffusion) and Rm (the ratio between magnetic induction and magnetic diffusion) denote the …

Coherence and synchronization of noisy-driven oscillators
… the delayed feedback. We develop the analytical theory of this effect, considering noisy systems in the Gaussian approximation. Possible applications of the effect for the synchronization control are also discussed. Second, we consider synchrony of limit cycle systems (in other words, …

Mathematical problems arising in interfacial electrohydrodynamics
In this work we consider the nonlinear stability of thin films in the presence of electric fields. We study a perfectly conducting thin film flow down an inclined plane in the presence of an electric field which is uniform in its undisturbed state, and normal to the plate at infinity. In addition, …
