| Abstract: | A detailed investigation of Gauss-Bonnet theory has been done from a different perspective. At first, the standard energy
conditions are discussed and modified forms have been presented. Then some cosmological solutions have been obtained in 5D
for perfect fluid assuming that the extra dimensional metric coefficient decreases with time. For some particular choice of
the parameters, exponential solutions are obtained and finally, Cosmic No-Hair Conjecture has been proved for Gauss-Bonnet
dilatonic scalar coupled to Einstein gravity with coupling parameter growing linearly in time. |
