## 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 $R$ but higher scalar powers of the Riemann curvature tensor.

When viewing Einstein-Hilbert gravity as an effective field theory valid at low energy, 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.
