Title: A power saving for planar halving lines.

Abstract: There are absolute constants ε > 0 and C such that every sufficiently large even n-point set in the plane with no three collinear has at most $Cn{}{4/3-{}varepsilon}$ unordered halving pairs. This gives a power saving over the classical $O(n{}{4/3})$ bound for planar halving lines. The proof is nonquantitative and does not supply explicit constants.

This abstract is a catalogue record. It is not a verification and not a premise. It does not close O.1. O.1 stays NOT_CLOSED. No quantum coefficient is admitted. No compilation is asserted.
