The action of a Backlund-Darboux transformation on a spectral problem associated with a known integrable system can define a new…
Blowup in finite time for nonlinear Schrodinger equations (NLS) with inverse-square potential a|x| −2 and nonlocal nonlinearities…
Coherent detection employing multilevel modulation formats has become one of the most promising technologies for next generation…
We develop a modulation theory model based on a Lagrangian formulation to investigate the evolution of dark and gray optical…
In this paper we solve a system of nonlinear algebraic equations (NAEs) of a vector-form: F(x) = 0. Based-on an invariant…
In this paper, the water wave flow problem for an incompressible and inviscid fluid of constant depth is studied under the…
In magnetohydrodynamics with Hall effect (Hall-MHD), weakly nonlinear quasimonochromatic dispersive Alfven waves propagating…
This thesis deals with the propagation of optical waves in Kerr nonlinear media, with emphasis on optical beam propagation beyond…
We consider static, cylindrically symmetric configurations in general relativity coupled to nonlinear electrodynamics (NED) with…
Optical soliton propagation in fibres with resonant impurities and erbium-doped nonlinear systems are considered. The fibre…
