Abstract

In this study, we present a numerical method to solve the Regularized Long Wave (RLW) equation,
based on cubic B-spline quasi-interpolation for the space integration and Crank-Nicolson method
for the time integration. The method is tested on the problems of propagation of a solitary wave
and interaction of two solitary waves. The three conservation quantities of the motion are calculated
to determine the conservation properties of the proposed algorithm.

Keywords
