Abstract:
We derive the Lagrangians of the higher-order Painlevé equations using Jacobi’s last multiplier technique. Some of these higher-order differential equations display certain remarkable properties like passing the Painlevé test and satisfy the conditions stated by Jurás̆, thus allowing for a Lagrangian description.
Key words:
Higher-order Painlevé equation, Painlevé test, Lagrangian, Jurás̆ conditions.
