Error Estimate for a Fully Discrete Spectral Scheme for Korteweg-de Vries-Kawahara Equation

U. Koley

We are concerned with the convergence of spectral method for the numerical solution of the initial-boundary value problem associated to the Korteweg-de Vries-Kawahara equation (in…

Operator splitting for the Benjamin-Ono equation

R. Dutta, H. Holden, U. Koley +1

In this paper we analyze operator splitting for the Benjamin-Ono equation, u_t = uu_x + Hu_xx, where H denotes the Hilbert transform. If the initial data are sufficiently regular,…

An error estimate for the finite difference approximation to degenerate convection -diffusion equations

K. H. Karlsen, U. Koley, N. H. Risebro

We consider semi-discrete first-order finite difference schemes for a nonlinear degenerate convection-diffusion equations in one space dimension, and prove an L1 error estimate. Pr…

Finite difference schemes for the symmetric Keyfitz-Kranzer system

U. Koley, N. H. Risebro

We are concerned with the convergence of numerical schemes for the initial value problem associated to the Keyfitz-Kranzer system of equations. This system is a toy model for sever…

Multilevel Monte Carlo for Random Degenerate Scalar Convection Diffusion Equation

U. Koley, N. H. Risebro, Ch. Schwab +1

We consider the numerical solution of scalar, nonlinear degenerate convection-diffusion problems with random diffusion coefficient and with random flux functions. Building on recen…
