H\"older regularity for Maxwell's equations under minimal assumptions on the coefficients [PDF]
We prove global H\"older regularity for the solutions to the time-harmonic anisotropic Maxwell's equations, under the assumptions of H\"older continuous coefficients. The regularity hypotheses on the coefficients are minimal. The same estimates hold also

Well-posedness for a higher order nonlinear Schrodinger equation in Sobolev spaces of negative indices [PDF]
We prove that, the initial value problem associated to u_{t} + i\alphau_{xx} + \beta u_{xxx} + i\gamma |u|^{2}u = 0, x,t \in R, is locally well-posed in Sobolev spaces H^{s} for s>-1 ...

On a system of multi-component Ginzburg-Landau vortices
We study the asymptotic behavior of solutions for nn-component Ginzburg-Landau equations as ε→0\varepsilon \to 0. We prove that the minimizers converge locally in any Ck{C}^{k}-norm to a solution of a system of generalized harmonic map equations.

Normalized multi-bump solutions for saturable Schrödinger equations
In this paper, we are concerned with the existence of multi-bump solutions for a class of semiclassical saturable Schrödinger equations with an density function:

Born‐infeld electrodynamics: Clifford number and spinor representations
The Clifford number formalism for Maxwell equations is considered. The Clifford imaginary unit for space‐time is introduced as coordinate independent form of fully antisymmetric fourth‐rank tensor. The representation of Maxwell equations in massless Dirac equation form is considered; we also consider two approaches to the invariance of Dirac equation ...

Uncountably Many Solutions for Nonlinear Helmholtz and Curl-Curl Equations
We obtain uncountably many solutions of nonlinear Helmholtz and curl-curl equations on the entire space using a fixed point approach. The constructed solutions are mildly localized as they lie in the essential spectrum of the corresponding linear ...

Iterative solution of quadratic tensor equations for mutual polarisation
To describe mutual polarisation in bulk materials containing high polarisability molecules, local fields beyond the linear approximation need to be included. A second order tensor equation is formulated, and it describes this in the case of crystalline or at least locally ordered materials such as an idealised polymer. It is shown that this equation is

This research is based on three main pillars which are studying the computational solutions of the modified Benjamin–Bona–Mahony (BBM) equation via the modified Khater method then investigating the stability property of the obtained solutions through the
