Abstract

AbstractWe show that many independent scenarios as the âaccelerated expansion of the universeâ, âeternal inflationâ, âeternally oscillating universeâ, ânonsingular oscillating universeâ, and âcollapse of an oscillating universeâ may occur without modifying the gravity theory or introducing scalar fields of any type. This is achieved by replacing the standard Lagrangian in the Friedmann-Robertson-Walker spacetime model by an exponentially nonstandard Lagrangian which modify the Euler-Lagrange equation although the standard variational approach is used.PACS45.20.Jj; 98.80.-k
