Description
This work aims to study gravitational waves in the primordial universe. Using the
short wave approximation, it is possible to find the propagation equations of gravitational
waves in a curved background. These equations make it possible to find the gravitational
waves emitted in the primordial universe, using the FLRW metric, which is the standard
metric for cosmology studies.
