چکیده

The objective of this paper is two-fold: firstly, we develop a local and global (in time) wellposedness theory for a system describing the motion of two fluids with different densities under capillary-gravity waves in a deep water flow (namely, a Schrödinger-Benjamin-Ono system) for lowregularity initial data in both periodic and continuous cases; secondly, a family of new periodic traveling waves for the Schrödinger-Benjamin-Ono system is given: by fixing a minimal period we obtain, via the implicit function theorem, a smooth branch of periodic solutions bifurcating a Jacobian elliptic function called dnoidal, and, moreover, we prove that all these periodic traveling waves are nonlinearly stable by perturbations with the same wavelength.

Time-Periodic Solutions of the Benjamin-Ono Equation

We present a spectrally accurate numerical method for finding non-trivial timeperiodic solutions of non-linear partial differential equations. The method is based on minimizing a functional (of the initial condition and the period) that is positive unless the solution is periodic, in which case it is zero. We solve an adjoint PDE to compute the gradient of this functional with respect to the in...

On Periodic Traveling Waves for the Klein-gordon-schrödinger System with Yukawa Interaction

The main purpose of this paper is to investigate the existence and orbital stability of a two–parameter family of periodic waves related to the Klein-Gordon-Schrödinger system with Yukawa interaction. The existence of periodic waves is deduced from the Implicit Function Theorem and the orbital stability is obtained from arguments due to Benjamin&Bona&Weinstein.

Global Paths of Time-Periodic Solutions of the Benjamin-Ono Equation Connecting Arbitrary Traveling Waves

We classify all bifurcations from traveling waves to non-trivial time-periodic solutions of the Benjamin-Ono equation that are predicted by linearization. We use a spectrally accurate numerical continuation method to study several paths of non-trivial solutions beyond the realm of linear theory. These paths are found to either re-connect with a different traveling wave or to blow up. In the lat...

Well-posedness and standing waves for the fourth-order non-linear Schrödinger-type equation

We consider the initial value problem for the fourth-order non-linear Schrödinger-type equation (4NLS) which describes the motion of an isolated vortex filament. In the first part of this note we review some recent results on the time local well-posedness of (4NLS) and give the alternative proof of those results. In the second part of this note we consider the stability of a standing wave solut...
