Application of a Lie group admitted by a homogeneous equation for group classification of a corresponding inhomogeneous equation

摘要

This paper proposes an algorithm for group classification of a nonhomogeneous equation using the group analysis provided for the corresponding homogeneous equation. The approach is illustrated by a partial differential equation, an integro-differential equation, and a delay partial differential equation. (C) 2017 Elsevier B.V. All rights reserved.
