Title: Approximate Noether symmetries and approximate conservation laws
Abstract:
Within the framework of the recently introduced consistent approach for approximate Lie symmetries of differential equations, approximate Noether symmetries of variational problems involving small terms are considered. Then, an approximate Noether theorem leading to the construction of approximate conservation laws for models admitting a perturbed Lagrangian function is stated. Some illustrative applications are presented.
