Continuous data assimilation for 2D stochastic Navier-Stokes equations

Hakima Bessaih, Benedetta Ferrario, Oussama Landoulsi +1

Continuous data assimilation methods, such as the nudging algorithm introduced by Azouani, Olson, and Titi (AOT) [2], are known to be highly effective in deterministic settings for…

The distorted Fourier transform for the linearized Gross-Pitaevskii equation in the Hyperbolic plane

Oussama Landoulsi, Sohrab Shahshahani

Motivated by the stability problem for Ginzburg-Landau vortices on the hyperbolic plane, we develop the distorted Fourier transform for a general class of radial non-self-adjoint m…

Equivariant stability of vortices in Manton's Chern-Simons-Schrödinger system on the hyperbolic plane

Oussama Landoulsi, Sohrab Shahshahani

In this work we study magnetic vortices on the hyperbolic plane for a Chern-Simons-Schrödinger system introduced by Manton. The model can be thought of as the Schrödinger analogue…

Threshold solutions in the focusing 3D cubic NLS equation outside a strictly convex obstacle

Thomas Duyckaerts, Oussama Landoulsi, Svetlana Roudenko

We study the dynamics of the focusing cubic nonlinear Schrödinger equation in the exterior of a strictly convex obstacle at the mass-energy threshold, namely, when $ E_Ω[u_0]…

Construction of solitary wave solution of the nonlinear focusing schrödinger equation outside a strictly convex obstacle for the -supercritical case

Oussama Landoulsi

We consider the focusing -supercritical Schrödinger equation in the exterior of a smooth, compact, strictly convex obstacle. We construct a solution behaving asymptotically as…
