Rogier Crijns,Nina Dörner,Philip Langn use eqs. (1.141) and (1.169) and integrate eq. (1.199) to obtain the corresponding Einstein frame solutions. In practice the reverse path is sometimes followed, i.e., exact solutions of general relativity are mapped back into the Jordan frame to obtain exact solutions in this representation.VOC 发表于 2025-3-23 21:03:10

Perturbations,ed density perturbations. Their physical wavelengths λ. = aλ (where A is the comoving wavelength) scale as the scale factor a, while the horizon size . stays almost constant during inflation. As a consequence, perturbations cross outside the horizon during inflation. The spectrum of density perturba
