Abstract. We propose a new class of uniformly accurate splitting methods for the Benjamin– Bona-Mahony equation which converge uniformly in the dispersive parameter ε. The proposed splitting schemes are furthermore asymptotic convergent and preserve the KdV limit. We carry out a rigorous convergence analysis of the splitting schemes exploiting the smoothing properties in the system. This will allow us to establish improved error bounds with gain either in regularity (for non smooth solutions…

Time integrators for dispersive equations in the long wave regime
We introduce a novel class of time integrators for dispersive equations which allow us to reproduce the dynamics of the solution from the classical ε = 1 up to long wave limit regime ε ≪ 1 on the


Uniformly accurate exponential-type integrators for Klein-Gordon equations with asymptotic convergence to the classical NLS splitting
This work introduces efficient and robust exponential-type integrators for Klein-Gordon equations which resolve the solution in the relativistic regime as well as in the highly-oscillatory non-relativists regime without any step-size restriction, and derives uniform convergent schemes under far weaker regularity assumptions on the exact solution.
Artificial boundary conditions for the linearized Benjamin–Bona–Mahony equation
This paper derives explicit transparent boundary conditions both continuous and discrete for the linearized BBM equation and uses these boundary conditions to compute solutions with compact support in the computational domain and also in the case of an incoming plane wave.

A new scheme for the integration of the periodic nonlinear Schrodinger equation is proposed and rigorously prove convergence rates at low regularity, based on discrete Bourgain space estimates which are introduced in this paper.

A new general framework for the approximation of evolution equations at low regularity is introduced and a new class of schemes for a wide range of equations under lower regularity assumptions than classical methods require are developed.

Operator splitting for partial differential equations with Burgers nonlinearity
It is shown that the Strang splitting method converges with the expected rate if the initial data are sufficiently regular and for the KdV equation, second-order convergence in H^r for initial data in $H^{r+5}$ with arbitrary $r\ge 1$.
Convergence error estimates at low regularity for time discretizations of KdV
We consider various filtered time discretizations of the periodic Korteweg–de Vries equation: a filtered exponential integrator, a filtered Lie splitting scheme as well as a filtered resonance based
