Noether symmetry approach in Eddington-inspired Born–Infeld gravity
European Physical Journal C: Particles and Fields, 2021 In this work, we take a short recap of a formal framework of the Eddington-inspired Born–Infeld (EiBI) theory of gravity and derive the point-like Lagrangian for underlying theory based on the use of Noether gauge symmetries (NGS).
