Idea

In the context of gravity (general relativity), higher curvature corrections are modifications of the Einstein-Hilbert action that include not just the linear appearance of the scalar curvature RR but higher scalar powers of the Riemann curvature tensor.

When viewing Einstein-Hilbert gravity as an effective field theory valid at low energy/long wavelengths, then higher curvature corrections are precisely the terms that may appear at higher energy in pure gravity. Notably the effective field theories induced by string theory come with infinite towers of higher curvature corrections.

In the context of cosmology, higher curvature corrections are a candidate for the inflaton field, see at Starobinsky model of cosmic inflation.

A spacetime that extremizes the Einstein-Hilbert action for given cosmological constant and arbitrary higher curvature correction is called a universal spacetime.

Examples

For 11d Supergravity

A systematic analysis of the possible supersymmetric higher curvature corrections of D=11 supergravity makes the I8-characteristic 8-form

I 8(R)≔148(p 2(R)−(12p 1(R)) 2)∈Ω 8 I_8(R) \;\coloneqq\; \tfrac{1}{48} \Big( p_2(R) \;-\; \big( \tfrac{1}{2} p_1(R)\big)^2 \Big) \;\; \in \Omega^8

(a differential form built from the Riemann curvature, expressing a polynomial in the first and second Pontryagin classes, see at I8) appear as the higher curvature correction at order ℓ 6\ell^6, where ℓ\ell is the Planck length in 11d (Souères-Tsimpis 17, Section 4).

At this order, the equation of motion for the supergravity C-field flux G 4G_4 and its dual G 7G_7 is (Souères-Tsimpis 17, (4.3))

(1)dG 7(ℓ)=−12G 4(ℓ)∧G 4(ℓ)+ℓ 6I 8(R), d G_7(\ell) \;=\; -\tfrac{1}{2} G_4(\ell) \wedge G_4(\ell) + \ell^6 I_8(R) \,,

where the flux forms themselves appear in their higher order corrected form as power series in the Planck length

G 4(ℓ)=G 4+ℓ 6G 4 (1)+⋯ G_4(\ell) \;=\; G_4 + \ell^6 G_4^{(1)} + \cdots

G 7(ℓ)=G 7+ℓ 6G 7 (1)+⋯ G_7(\ell) \;=\; G_7 + \ell^6 G_7^{(1)} + \cdots

(Souères-Tsimpis 17, (4.4))

Beware that this is not the lowest order higher curvature correction: there is already one at 𝒪(ℓ 3)\mathcal{O}(\ell^3), given by ℓ 3G 4∧12p 1(R)\ell^3 G_4 \wedge \tfrac{1}{2}p_1(R) (Souères-Tsimpis 17, Section 3.2). Hence the full correction at 𝒪(ℓ 3)\mathcal{O}(\ell^3) should be the further modification of (2) to (cf. Tsimpis 2004, p. 8):

(2)dG 7(ℓ)=−12G 4(ℓ)∧(G 4(ℓ)−12p 1(R))+ℓ 6I 8(R). d G_7(\ell) \;=\; -\tfrac{1}{2} G_4(\ell) \wedge \big( G_4(\ell) - \tfrac{1}{2} p_1(R) \big) + \ell^6 I_8(R) \,.
