Resumo
The purpose of this work is to carry out a review on Noether’s theorem, based on the Lagrangian and Hamiltonian formalisms, exploring symmetries of this system, as well as their respective conserved quantities. Such quantities are obtained by the theorem, in different applications, from simple cases such as that of a free particle and a harmonic oscillator, to studies associated with Brans-Dicke’s cosmology and the Einstein-aether model. So, with a view to a good review and a notion of applicability in the context of gravitation, we sought to develop more complex cases, as well as to analyze possible applications in future projects.
