★ Starobinsky inflation

In the USSR, Alexei Starobin notes that quantum corrections to General relativity should be important for the early Universe. These generically lead to curvature-squared corrections to Einstein–Hilbert action in the form of f R modified gravity. The solution to the Einstein equations in the presence of curvature squared terms, when the curvatures of a few large, leads to an effective cosmological constant. He therefore suggested that the early universe went through an era of inflationary de sitter. It enabled us to solve problems of cosmology and led to specific predictions for the corrections to the microwave background radiation, corrections which were then calculated to the last detail. Starobin action

S = 1 2 κ ∫ R + R 2 6 M 2 | g | d 4 x, {\displaystyle S={\frac {1}{2\kappa }}\int \leftR+{\frac {R^{2}}{6M^{2}}}\right{\sqrt {\vert g\vert }}\,\mathrm {d} ^{4}x,}

where κ = 8 π G / Z 4 {\the style property display the value of \Kappa =8\PI g / C^{4}} and R {\the style property display the value of R} is the Ricci scalar. This action corresponds to the potential v ϕ = Λ 4 1 − e − 2 / ϕ 3 / m p 2 {\the style property display the value in\PHI=\type ^{4}\left1-e^{- {this:\sqrt {2 / 3}}\PHI /if{p}}\right^{2}} in the Einstein frame.
