报告提纲

• We discussed the evolution of cosmological gravitational wave showing how the cosmological background affects their dynamics.

• The detection of cosmological gravitational wave could constitute an extremely important signature to discriminate among different cosmological models.

• We considered the cases of scalar-tensor gravity and F(R) gravity where it is demonstrated the amplification of gravition amplitude charge if compared with General Relativity.

• We also show the speed of the gravitational wave by the modified gravity does not change different from the scalar tensor theory without higher derivative couplings.

• We derived the governing equation for gravitational waves propagating in a fluid with bulk viscosity ζ and shear viscosity η.
