Linearization Problem for a System of Two Second-Order ODEs via Cartan's Method: Branch I
Batoul M. Raddad, Ahmad Y. Al-Dweik, Marwan Aloqeili +1
Cartan's method classifies the class of linearizable system of two second-order ODEs into many branches. This paper investigates Branch I of the classification, characterized by a…

Equivalence Problem for Non-Linearizable Fourth-Order ODEs with Five-Dimensional Lie Symmetry subalgebra via Inductive Cartan Equivalence Method
Sondos R. Khalil, Ahmad Y. Al-Dweik, Marwan Aloqeili +1
Four coframes of invariant 1-forms are explicitly constructed using the Inductive Cartan equivalence method with rank zero corresponding to four distinct branches. These coframes a…
