The Lie-group method based on radial basis functions for solving nonlinear high dimensional generalized Benjamin–Bona–Mahony–Burgers equation in arbitrary domains

Abstract: The aim of this paper is to introduce a new numerical method for solving the nonlinear generalized Benjamin-Bona-Mahony-Burgers (GBBMB) equation. This method is combination of group preserving scheme (GPS) with radial basis functions (RBFs), which takes advantage of two powerful methods, one as geometric numerical integration method and the other meshless method. Thus, we introduce this method as the Lie-group method based on radial basis functions (LG-RBFs). In this method, we use Kansas approach to approxima… Show more

“…The goal is to take advantage of both meshless method and GNI method for numerical approximations obtained by this combination of the Lie-Group method based on radial basis functions (LG-RBFs). This method has been recently applied to the Heat equation [24] and high-dimensional generalized Benjamin-Bona-Mahony-Burgers' equation [25] .…”

“…In special case, if = 0, = 1 and = −1 then the problem acquired to the regularized long-wave equation (RLWE) that was studied as an improvement of the Korteweg-de Vries (KdV) equation for modeling long surface gravity waves. Various methods (analytical and numerical) have been applied for solving the BBMB equation [32][33][34][35][36][37][38][39]. Our goal is to deal with the GBBMB through the SBM in order to acquire more accurate results in comparison with other methods.…”
