Query: Size of the Gribov region in curved spacetime   Recent work in the literature has argued that the joint effect of spacetime
curvature and the Gribov ambiguity may introduce further modifications to the
Green functions in the infrared. This paper focuses on a simple criterion for
studying the effect of spacetime curvature on the size of the Gribov region,
improving the accuracy of the previous analysis. It is shown that, depending on
the sign of the scalar and Riemann curvature, the Gribov horizon moves inward
or, instead, outward with respect to the case of flat spacetime. This is made
clear by two novel inequalities here derived for the first time.
