Complete group classification of systems of two linear second‐order ordinary differential equations: the algebraic approach

Abstract: We give a complete group classification of the general case of linear systems of two second-order ordinary differential equations. The algebraic approach is used to solve the group classification problem for this class of equations. This completes the results in the literature on the group classification of two linear second-order ordinary differential equations including recent results which give a complete group classification treatment of such systems. We show that using the algebraic approach leads to the … Show more

“…This result has been stated as a Theorem in Section 5 of the paper. The results were discussed and in two or more of the cases which had the admitted generators of the form X A the study was similar to that done in the earlier studies in [1,2,3,4]. A detailed discussion on systems admitting generators of the form X A has been given in Section 6 of the paper.…”

“…After Lie, several researchers have been involved in analysis of different aspects of this work; see [1,6,[8][9][10][11][12]. Although the algebraic approach is more involved, it generates new cases and more insight to mathematical properties whose base is algebra (see [8,9,13,14]). Thus the classification of differential equations via algebraic approach is more efficient than other classical approaches.…”
