Description
In order to regularize the energy of point-like charged
particles, Born and Infeld introduced a modification of the
Maxwell lagrangian that naturally imposes an upper bound on
electromagnetic fields. This approach was later taken by
Deser and Gibbons to propose an analogous modification for
gravity. I will review some of these ideas as well as some
extensions for the gravitational sector. Finally, a scenario
where inflation could be supported by a set of massive
particles within the context of these theories will be
discussed.
