An Improved Bound for Weak Epsilon-nets in the Plane

We show that for any finite point set P in the plane and ϵ > 0 there exist O(ϵ3/12+γ ) points in R2, for arbitrary small γ > 0, that pierce every convex set K with |K ∩ P| ≥ ϵ|P|. This is the first improvement of the bound of O(ϵ12 ) that was obtained in 1992 by Alon, Bárány, Füredi, and Kleitman for general point sets in the plane.
