De Sitter-like configurations with asymptotic quintessence environment
Roberto Giambò, Orlando Luongo
We examine a spherically-symmetric class of spacetimes carrying vacuum energy, while considering the influence of an external dark energy environment represented by a non-dynamical…

Fixed energy solutions to the Euler-Lagrange equations of an indefinite Lagrangian with affine Noether charge
Erasmo Caponio, Dario Corona, Roberto Giambò +1
We consider an autonomous, indefinite Lagrangian admitting an infinitesimal symmetry whose associated Noether charge is linear in each tangent space. Our focus lies in investigatin…
