Conservation Laws for a Variable Coefficient Variant Boussinesq System
Abstract and Applied Analysis, 2014 We construct the conservation laws for a variable coefficient variant Boussinesq system, which is a third-order system of two partial differential equations. This system does not have a Lagrangian and so we transform it to a system of fourth-order, which
